Coding Accuracy Support System (CASS) is a certification system from the United States Postal Service (USPS) for address validation. Our CASS-certified address validation service standardizes your mailing lists, updates outdated addresses, and verifies that your addresses are valid and complete. The DIY Portal instantly standardizes, corrects, updates, and verfies the addresses in your file and returns your file in minutes.

Maximize address quality, minimize mailing cost. Delivery information is only as good as the quality of the address data. Our goal is to help customers send their mail to the correct address every time. CASS address standardization provides added product value and service offerings that enable our customers to better manage the quality of their mailing lists while maximizing the ability to deliver mail as addressed.

Yes! Ensuring every mail piece you send is deliverable, means you will not waste money for returned pieces or mail sent to a vacant address. Also, by using CASS address standardization you may qualify for postage discounts for every single mail piece when pre-sorting the mail for the USPS.

When opting for real-time processing, the DIY Portal can process thousands of records per minute, and files are returned within minutes or hours based on the total record count.

It only costs $1.30 for every 1,000 input records, or $0.0013 per record. For less than a penny a record the cost for processing is easily recovered when you're not sending undeliverable mail.

Yes, however it is a different service. Additional details can be found on our Canadian Address Standardization (SERP) page.

The DIY Portal helps identify movers in your customer databases or mailing lists, using a combination of names and addresses. To identify a match, the portal must recognize your customer’s first and last name against the NCOA database’s first and last name and old address on file. The output file will then contain the new address for your customer.

For SERP address standardization the price is $1.50 for every thousand records, or $0.0015 per record submitted.

For NCOA the price is $2.90 for every thousand records, or $0.0029 per record submitted.

Please create a free account to log into the DIY Portal and view the complete pricing list for Canadian data services.

The database used for Canadian SERP and Canadian NCOA is updated on a monthly basis.

If you are preparing a mailing and do not have an existing business relationship with a customer you can update your mailing list with the new address information. You cannot keep the mover data on file and must re-process your mailing list against NCOA mover data services for any subsequent mailing.

If you have an existing relationship with a customer you can update your customer records with the new address information. When a new address is provided, terms of use also allow you to contact the customer to confirm the new address information.

Delivery Sequence File (DSF2) processing updates your data by identifying known addresses and specific address attributes, and returning a walk sequence and a business/residential flag for each record that is matched. This information can be used to hone your mailing lists and produce mailings that are targeted more precisely.

Maximize address quality, minimize mailing cost. Delivery information is only as good as the quality of the address data. Our goal is to help customers send their mail to the correct address every time. DSF2 provides added product value and service offerings that enable our customers to better manage the quality of their mailing lists while maximizing the ability to deliver mail as addressed.

By using DSF2 you will qualify for postage discounts for every single mail piece when sorting by walk distance and using Delivert Point Validation (DPV) addresses.

When opting for real-time processing, the DIY Portal can process thousands of records per minute, and files are returned within hours.

It only costs $1.40 for every 1,000 input records, or $0.0014 per record. For less than a penny a record the cost for processing is easily recovered when qualifying and using the postal discounts DSF2 provides.

DSF2 only requires a mailing address. However, if your list contains name information as well we always recommend ordering NCOA^Link along with DSF2 .

The following fields and values are returned based on the Change Of Address (COA) address if a change of address match was made; otherwise they are based on the input address.

Seasonal Address Flag

Y = Seasonal Address

N = Not a Seasonal Address

When opting for real-time processing, the DIY Portal can process hundreds of records per minute, and files are returned within hours.

The database used for email appending is updated weekly.

Full name, or last name, and the 5 digit zip code is required to processing a file through email appending services.

If 5 digit zip code is not available, you can alternatively substitute the city and state in place of the zip code. If city and state are included without a zip code, an attempt will be made to obtain the zip code using the city and state. For multi-zip cities the primary zip code will be used. This may affect the accuracy of the confidence levels returned.

We have over 198 million marketable email records, and a bounce/suppression file of over 300 million records, that are multi-sourced from over 2 billion input records in total.

Our standard email append processing includes a 7-step email validation that queries the receiving email box to ensure deliverability. In otherwords, we guarantee that the emails we append to each of your records are deliverable.

We only charge for deliverable emails appended to your file, which is currently $0.12 per email address. Please create a free account to log into the DIY Portal and view the complete pricing list for email append services.

Performing an email append is as simple as uploading your customer file, mapping your name and address fields, and clicking submit. We also have some "How To" videos in the DIY Portal to show you exactly how to process a file.

Since your records have various data fields missing or available, you could pick and choose several of our other services to populate and update your records to capture any missing data.

As an example, our Reverse Phone Append service will allow you to submit a file populated with only phone numbers to append names and addresses. Once the names and addresses have been appended, you can then run your file through our email append service with the required name and address fields.

Yes, we have a proprietary and comprehensive 7-step validation process which flags potential undeliverable email addresses, autocorrects syntactical errors, and identifies spam traps, complainers, and more. In otherwords, we'll validate the email mailbox and verify if it can receive email which allows us to guarantee you that the email addresses are deliverable.

The Processing Acknowledgement Form (PAF) is a requirement of the U.S. Postal Service. It is to ensure that NCOA^Link is used only for the purposes of mailing. All NCOA^Link vendors are required to have a completed and signed PAF provided by the list owner. In no case may a broker, agent, or third party sign as the list owner. Mailing lists cannot be processed until we receive a completed and signed PAF.

The difference between 18-Month and 48-Month processing is the number of months of change of address data that is available. Depending on the last time your data was processed through NCOA^Link you may only need 0-18 month moves. If the list has never been processed through NCOA^Link, 48-Month processing is recommended since it will also return 19-48 month moves.

The U.S. Postal Service is responsible for creating and maintaining the NCOA^Link file. Moves are reported by individuals, families, and businesses who have completed a change of address form.

When opting for real-time processing, the DIY Portal can process 10,000 records per minute.

The NCOA^Link database is updated weekly.

Change of address requests are kept for 48 months / 4 years.

To qualify for postage discounts it's required that you update your files every 95 days. Therefore, many users update their lists, database, and/or mail files every 2 to 3 months.

The STD address lines are the standardized version of the address. The COA fields contain the change of address data for the new address output from the NCOA database. The new address data in the COA fields should be used first, and when there is no COA data present then the STD address data should be used as that data is a properly formatted and standardized version of the address.

NCOA^Link is a process that matches a file of names and addresses to the USPS licensed NCOA^Link database comprised of 160+ million records of individual, family, and business moves. DSF2 is a USPS licensed database that improves delivery of your mailings by examining address data and comparing it to the DSF2 database that contains each of the 145+ million delivery points. DSF2 confirms the existence of the address, provides delivery type, business versus residential, and provides a Pseudo Sequence Number to qualify for walk sequence postal presort discounts. DSF2 detects potentially undeliverable addresses for reasons other than Change Of Address (COA).

If DSF2 is what you need instead of NCOA^Link, we also offer DSF2 Processing.

When people move and change addresses, not everyone completes and registers this Change Of Address (COA) with the USPS. Without this registration, the move is not recorded in the NCOA^Link database, and therefore no forwarding address can be provided. However, by using PCOA services we can search beyond the boundaries of NCOA^Link alone.

The PCOA database is compiled from multiple private sources, such as magazine publishers and credit card companies. Often these companies will receive change-of-address notifications that are not reported to the USPS. This allows you the opportunity to update your database and stay in contact with your customers who might otherwise become undeliverable records on your marketing database.

It is always recommended that you run PCOA (Private Change of Address) in conjunction with NCOA^Link, rather than as a standalone service. NCOA^Link is still the best method to capture the most moves and is required in order to meet the USPS Move Update Requirements.

All records processed through NCOA^Link will receive a return code. This return code will provide you information about what NCOA^Link type of match was found for each record.

Return Code: A – Change Of Address (COA) Match

The input record matched to a business, individual, or family type master file record. A new address from NCOA^Link is returned.

Return Code: 00 – NO Match

The input record COULD NOT BE matched to a NCOA^Link master file record. A new address from NCOA^Link could not be furnished. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 01 – Found Change Of Address (COA): Foreign Move

The input record matched to a business, individual, or family type NCOA^Link master file record but the new address was outside the USPS delivery area. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 02 – Found Change Of Address (COA): Moved Left No Address (MLNA)

The input record matched to a business, individual, or family type NCOA^Link master file record and the new address was not provided to USPS. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 03 – Found Change Of Address (COA): Box Closed No Order (BCNO)

The input record matched to a business, individual, or family type NCOA^Link master file record which contains an old address or PO BOX that has been closed without a forwarding address provided. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 04 – Cannot Match Change Of Address (COA): Street Address With Secondary

In the STANDARD mode utilizing Family matching logic the input record matched to a family record type on the NCOA^Link master file with an old address that contained secondary information which obtained a ZIP + 4 street level match. The input record does not contain secondary information. This address match situation requires individual name matching logic to obtain a NCOA^Link match and individual names do not match.

Return Code: 05 – Found Change Of Address (COA): New 11-Digit Delivery Point Barcode (DPBC) Is Ambiguous

The input record matched to a business, individual, or family type NCOA^Link master file record. The new address on the master file record could not be converted to a deliverable address because the Delivery Point Barcode (DPBC) represents more than one delivery point. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 06 – Cannot Match Change Of Address (COA): Conflicting Directions: Middle Name Related

There is more than one Change Of Address (COA) (individual or family type) record for the match algorithm and the middle names or initials on the COAs are different. Therefore, a single match result could not be determined. This return code is only obtained when using NCOA^Link individual matching logic.

Return Code: 07 – Cannot Match Change Of Address (COA): Conflicting Directions: Gender Related

There is more than one Change Of Address (COA) (individual or family type) record for the match algorithm and the genders of the names on the COAs are different. Therefore, a single match result could not be determined. This return code is only obtained when using NCOA^Link individual matching logic.

Return Code: 08 – Cannot Match Change Of Address (COA): Other Conflicting Instructions

The input record matched to two master file (business, individual or family type) records. The two records in the master file were compared and due to differences in the new addresses, a match could not be made. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 09 – Cannot Match Change Of Address (COA): High-Rise Default

The input record matched to a family record on the master file from a High-Rise address ZIP + 4 coded to the building default. This address match situation requires individual name matching logic to obtain a match and individual names do not match on the NCOA^Link file.

Return Code: 10 – Cannot Match Change Of Address (COA): Rural Default

The input record matched to a family record on the master file from a Rural Route or Highway Contract Route address ZIP + 4 coded to the route default. This address situation requires individual name matching logic to obtain a match and individual names do not match on the NCOA^Link file.

Return Code: 11 – Cannot Match Change Of Address (COA): Individual Match: Insufficient Change Of Address (COA) Name For Match

There is a NCOA^Link master file (individual or family type) record with the same surname and address but there is insufficient name information on the NCOA^Link master file record to produce a match using individual matching logic. This return code is only obtained when using individual matching logic.

Return Code: 12 – Cannot Match Change Of Address (COA): Middle Name Test Failed

The input record matched to an individual or family record on the NCOA^Link master file with the same address and surname. However, a match cannot be made because the input name contains a conflict with the middle name or initials on the NCOA^Link master file record. This return code is only obtained when using individual matching logic.

Return Code: 13 – Cannot Match Change Of Address (COA): Gender Test Failed

The input record matched to a NCOA^Link master file (individual or family type) record. A match cannot be made because the gender of the name on the input record conflicts with the gender of the name on the NCOA^Link master file record. This return code is only obtained when using individual matching logic.

Return Code: 14 – Found Change Of Address (COA): New Address Would Not Convert At Run Time

The input record matched to a NCOA^Link master file (business, individual, or family type) record. The new address could not be converted to a deliverable address. This return code may be returned regardless of the NCOA^Link processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 15 – Cannot Match Change Of Address (COA): Individual Name Insufficient

There is a NCOA^Link master file record with the same address and surname. A match cannot be made because the input record does not contain a first name or contains initials only. This NCOA^Link return code is only obtained when using individual matching logic.

Return Code: 16 – Cannot Match Change Of Address (COA): Secondary Number Discrepancy

The input record matched to a street level individual or family type NCOA^Link record. However, a match is prohibited based on 1 of the following reasons: 1) There is conflicting secondary information on the input and NCOA^Link master file record; 2) the input record contained secondary information and matched to a family record that does not contain secondary information. In item 2, this address match situation requires individual name matching logic to obtain a Change Of Address (COA) match and individual names do not match.

Return Code: 17 – Cannot Match Change Of Address (COA): Other Insufficient Name

The input record matched to an individual or family NCOA^Link master file record. The input name is different or not sufficient enough to produce a match. This NCOA^Link return code is only obtained when using individual matching logic.

Return Code: 18 – Cannot Match Change Of Address (COA): General Delivery

The input record matched to a family record on the NCOA^Link master file from a General Delivery address. This address situation requires individual name matching logic to obtain a NCOA^Link match and individual names do not match.

Return Code: 19 – Found Change Of Address (COA): New Address Not ZIP + 4 Coded, New Address Primary Number Not DPV Confirmable Or Temporary Change Of Address (COA)

There is a NCOA^Link change of address on file but the new address cannot be ZIP + 4 coded and therefore there is no 11-digit Delivery Point Barcode (DPBC) to store or return, the new address primary number cannot be confirmed on Delivery Point Validation (DPV) or the new address is temporary. This NCOA^Link return code may be returned regardless of the processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 20 – Cannot Match Change Of Address (COA): Conflicting Directions After Re-Chaining

Multiple NCOA^Link master file records were potential matches for the input record. The NCOA^Link master file records contained different new addresses and a single match result could not be determined. This NCOA^Link return code may be returned regardless of the processing mode, matching logic, or Change Of Address (COA) type.

Return Code: 66 – Daily Delete

The input record matched to a business, individual, or family type master file record with an old address that is present in the NCOA^Link daily delete file. The presence of an address in the NCOA^Link daily delete file means that a COA with this address is pending deletion from the NCOA^Link master file and that no mail may be forwarded from this address. This NCOA^Link return code may be returned regardless of the processing mode, matching logic or Change Of Address (COA) type.

Return Code: 91 – Change Of Address (COA) Match: Secondary Number Dropped From Change Of Address (COA)

The input record matched to a NCOA^Link master file record. The NCOA^Link master file record had a secondary number and the input address did not.

Return Code: 92 – Change Of Address (COA) Match: Secondary Number Dropped From Input Address

The input record matched to a NCOA^Link master file record, but the input address had a secondary number and the NCOA^Link master file record did not. The record is a ZIP + 4 street level match.

To process 48 Month NCOA it costs $1.70 for every 1,000 records ($0.0017 per record).
