Treasury Check Verification System Updates: Check Date, reCAPTCHA Verification and Application Programming Interface for Bulk Queries

May 20, 2021

As a reminder, all financial organizations that accept and negotiate U.S. Treasury checks are encouraged to use the Treasury Check Verification System (TCVS) (Off-site). TCVS allows financial organizations to submit Treasury check information to Treasury’s Bureau of the Fiscal Service (Fiscal Service) for the purpose of verifying that information. This information may assist or inform the financial organization in making its own determination of whether to accept and negotiate the Treasury check.

Single Check Queries

The elements required to query the status of a Treasury check in TCVS include:

  • Check symbol
  • Serial number
  • Dollar amount
  • Routing Transit Number of the financial institution conducting the query

Please note that the check date is now also required. See graphic below that shows where the date is found on a Treasury check.

Additionally, reCAPTCHA verification is now required for each check query.

Queries will still return one of the following responses:

  • Check Verified (if the symbol, serial number and amount are a match)
  • No Match (one of the elements are not a match or the check is expired)
  • Status: Issued, Paid, or Cancelled (if the check is not a match, no additional status information is provided)

If there is no issue record in TCVS, it does not mean the check is invalid. Please note TCVS was created as a tool to assist in fraud detection; financial organizations still need to verify that the check possesses the security features (Off-site PDF) of a Treasury check.

Bulk Queries

While the website should be used for single queries, TCVS also provides a more robust, secure Application Programming Interface (API) that enables automated real-time and bulk queries. Security controls prevent screen scraping and scripts for high-volume queries on the website, so use of the API is highly recommended for organizations processing high volumes of Treasury checks. Participation in TCVS through the secure API may be requested using the form posted under Terms and Conditions (Off-site) on the TCVS website.

The TCVS website is available from 6 a.m. to 12 a.m. ET, seven days a week. TCVS is available through the secure API 24 hours a day, seven days a week, except for a short daily maintenance window between 6 a.m. and 6:30 a.m. ET.
