GN 02402.353 Coding Samoan Bank Data on the Master Beneficiary Record (MBR)

This section describes how to code bank data for international direct deposit (IDD) of title II benefits to a financial institution in Samoa. Social Security Administration (SSA) stores bank data on the MBR in the same fields used for United States (U.S.) direct deposit. Special coding identifies the data as a Samoan direct deposit and allows SSA to route benefit payments through the Federal Reserve Bank of Kansas City (FRBKC) and the processor bank in Samoa to the beneficiary's FI.

NOTE: 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).

A. Where to obtain bank data

We receive requests to input bank data by mail, phone, or fax in the following formats:

  • a blank check,

  • an SSA-1199-OP30 International Direct Deposit Signup Form for Samoa, or

  • any documents that contains the required banking information.

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

B. Multi-country contract

The processing FI in Samoa will have a prefix of 66 at the beginning of the Routing and Transit Number (RTN). The first letter of the Depositor Account Number (DAN) field has the letter “O” assigned for Samoa.

C. Overview of IDD for Samoa

The beneficiary must provide complete information to DIO or the Federal Benefits Unit (FBU) for input. DIO will fax incomplete forms to the FBU that serves Samoa. The FBU contacts the beneficiary or FI for additional information.

D. Description of Samoan direct deposit bank data

The data for coding IDD for Samoa will come from banks the FRBKC has determined can handle the IDD process. The FRBKC identified and listed the participating banks on the International Treasury Services ( website as part of the ITS help file. If you do not have access to, you should refer to the listing in GN 02402.353G to verify bank codes when processing direct deposit to Samoan banks.

The IDD coding for Samoa bank data consists of up to 26 characters, including the country code of “O” for Samoa. The account number contains a:

  • nine-digit RTN 66000BBBX: where 66 is the country code field, position three through five are always zeros, BBB = three-digit bank code based on FI name (which you should verify as correct by checking the help file for assistance or the listing in GN 02402.353G), X = the check digit code; and

  • a 17-digit DAN OAAAAAAAAAAAAAAAA that consists of a one-digit country code of “O”, for Samoa, followed by an account number of 16-digits. If account number is less than 16 digits, add lead zeros (0) to make account number 16 digits.

NOTE: Account type when enrolling in International Treasury Services ( can be defaulted to checking if there is no indication of whether the account is a checking or a savings account.

E. Procedure for coding Samoan routing and account numbers

The FRBKC relies on SSA to provide the complete bank data to ensure correct posting of payments to a customer’s account. If the information is incomplete, the FRBKC will reject the payment and return the funds to SSA. You can code bank data for Samoa through when establishing or changing IDD or use an SSA system (i.e., POS, MACADE, etc.). When using, bank data will post to the MBR within four business days.

1. Initial award processing

If you are working on an initial award, you must update using the bank account information prior to processing the award to ensure that the beneficiary will receive his or her payment. If the complete bank account information is not in when the payment processes, the payment will reject and return to SSA.

2. Adding or updating bank data using SSA systems

If you use an SSA system (i.e., POS, MACADE) to add or update bank data to an MBR, do not input the bank account information into as the information will transfer to on the next business day.

NOTE: If it is within four business days of the current operational month (COM) cut-off date, use the procedure outlined below to code bank data to the MBR using an SSA system.




Are you coding an initial claim?

If yes, go to step 3.

If no, go to step 2.


Is the beneficiary's address on the MBR in a foreign country (PCOC = 8)?

If yes, go to step 3.

If no, STOP.

REASON: The MBR will not accept the International Direct Deposit (IDD) information.


To derive the nine-digit RTN for Samoa:

  • Start with 66 (the multi-country prefix SSA and FRBKC have designated to use for IDD to Samoa),

  • Code the three filler zeros “000”,

  • Code the three-digit bank code based on FI name after verifying accuracy against either the help file or the listing in GN 02402.353G of bank codes for Samoa.

  • Code the check digit code of the RTN, which you will obtain through Title II Interactive Comps.

    NOTE: The final digit is the U.S. check digit Code and is subject to change. Obtain check digit code through the Title II Interactive Comps from the Main Menus 07/Sub Menu 16.


Code the Type of Account as an “S” for savings or a “C” for checking. If no indicated account type, use a “C” for checking account.


For the first character of the DAN field, code an O followed by the 16-digit account number. If account number is less than 16 digits, add lead zeros (0) to make account number 16 digits.

NOTE: SSA does not have IDD for U.S. dollar accounts in Samoa.

F. Example of coding Samoan direct deposit

The customer provides us with a signup form for Samoa containing the following information:

  • Bank Name: Central Bank of Samoa

  • Bank Code 102, (based on SSA-1199 and confirming after checking the listing in GN 02402.354G)

  • Account Number: 1122334455667788

1. Derive the RTN as follows

  • Code the prefix of 66 (the multi-country prefix for Samoa).

  • Code three filler zeros “000”.

  • Code the three-digit bank code “102” based on FI name after checking the help file or see the listing in GN 02402.353G.

  • Code the one-digit check code (i.e., 8) (obtained from the Title II interactive Comps from the Main Menus 07/Sub Menu 16).

  • Code the type of account as a “C” for Checking or an “S” for Savings. If no type of account indicated, use a “C” for Checking.

2. Derive the DAN as follows

  • Use the letter “O” (for Samoa); and

  • The 16-digit account number “1122334455667788”.

The coder will obtain the following:

RTN: 660001028


DAN: O1122334455667788

The coding in POS will reflect:






The MBR will reflect the following information:

RTN-660001028 DAN-CO1122334455667788

(NOTE: The C in the DAN means that the account is a checking account.)
