GN 02402.335 Coding Trinidad and Tobago Bank Data for the MBR

A. Introduction

1. Coding Trinidad and Tobago Bank Data

This section describes how to code bank data for direct deposit of Title II benefits to a financial institution (FI) in Trinidad and Tobago. The bank data will be stored on the MBR in the same fields as are used for U.S. direct deposit. Special coding identifies the data as Trinidad and Tobago International Direct Deposit (IDD) and allows benefit payments to be routed through the Federal Reserve Bank of Kansas City (FRBKC) and Citibank to the beneficiary's FI in Trinidad and Tobago.


U.S. domestic (i.e., non-border) field offices (FOs) should not attempt to process an IDD request for this country. U.S. domestic FOs must forward all appropriate information to the Office of Earnings and International Operations, Division of International Operations (OEIO, DIO) for processing (For more information on forwarding IDD information, see GN 02402.205C, GN 01010.255, and GN 01702.310C).

2. Where to Obtain Data

The data for coding may come from a check, a signup form for Trinidad and Tobago (see GN 02402.335E.), or the equivalent information received by mail, phone, fax, or e-mail.


If upon receipt of the information, there are any discrepancies, follow instructions in GN 00203.020 and GN 02402.025.

3. Multi-Country Contract

Citibank is the processor bank for IDD to several countries, including Trinidad and Tobago. All Caribbean countries for which Citibank is the processor bank have a prefix of 70 at the beginning of the routing number (RTN) and an assigned letter in the first position of the Depositor Account Number (DAN). The letter assigned for Trinidad and Tobago is “R.”

B. Description – Trinidad and Tobago Bank Data

Trinidad and Tobago bank data consists of a total of up to 21 characters, as follows:

  • A 9-digit bank code (a zero, a 3-digit Bank Code, and a 5-digit Branch/Transit Code).

  • An account number of up to 12 characters.

C. Procedure

Follow the steps in this procedure to code direct deposit of Title II benefits to an FI in Trinidad and Tobago.

  1. 1. 

    Are you coding an initial claim?

    • If yes, go to step 3.

    • If no, go to step 2.

  2. 2. 

    Is the beneficiary's address on the MBR in a foreign country (PCOC = 8)? If no, STOP.

    REASON: The MBR will not accept IDD information (RTN begins with 5, 6, or 7) unless the address is in a foreign country.

  3. 3. 

    Code the type of account as Checking.

  4. 4. 

    Code the Routing and Transit Number field as follows:

    • Start with 70, the prefix assigned to Caribbean countries for which Citibank is the processor bank.

    • Code a zero, followed by the 3-digit Bank Code, followed by the first 2 digits of the Branch/Transit Code.

    • Code the U.S. check digit. Obtain the U.S. check digit by using the Check Digit program on Title II/Interactive Comps.

  5. 5. 

    Code the Depositor Account Number as follows:

    • Start with R, the letter assigned to show that the FI is in Trinidad and Tobago.

    • Code the remaining 3 digits of the branch code.

    • Code the account number. Do not include any dashes or spaces.

D. Examples

EXAMPLE 1: A signup form for Trinidad and Tobago contains the following information:

Bank code 0123. Branch code 45678. Account Number 123456789012.

  • The RTN will be 700123452. (The final digit, 2, is the U.S. check digit for 70012345.)

  • The DAN will be R678123456789012.

EXAMPLE 2: You receive a letter from Mr. Beneficiary asking for direct deposit to his account at a bank in Trinidad and Tobago. He gives the name and address of his bank, plus the following information: bank code 003, branch 12345, account number 1234567890. You check FRBKC's list of codes and find the codes are correct.

  • Code the RTN 700003129. (The final digit, 9, is the U.S. check digit for 70000312.)

  • Code the DAN R3451234567890.
