GN 02402.363 Coding Nauru 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 (FI) in Nauru. The Social Security Administration (SSA) stores bank data on the Master Beneficiary Record (MBR) in the same fields used for United States (U.S.) direct deposit. Special coding identifies the data as a Nauru direct deposit and allows SSA to route benefit payments through the Federal Reserve Bank of Kansas City (FRBKC) and the processor bank in Nauru 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,

  • a Form SSA-1199 (International Direct Deposit Signup Form for Nauru), see GN 02402.363G in this section, or

  • any document 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 Nauru 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 “N” assigned for Nauru.

C. Overview of IDD for Nauru

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 Nauru. The FBU contacts the beneficiary or FI for additional information.

D. Description of Nauru direct deposit data

The data for coding Nauru IDD for Nauru will come from FIs that the FRBKC has determined can receive IDD payments. The FRBKC identified and listed the participating FIs 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 02402.363H in this section to verify bank codes when processing direct deposit to Nauru FIs.

The IDD coding for Nauru FIs consists of up to 26 characters, including the country code of “N” for Nauru. The account number contains:

  • a 9-digit RTN 66000BBBX: where 66 is the country code field, positions 2 through 4 are filler “0”s, BBB= 3-digit bank code, X = the check digit code; and

  • a DAN NAAAAAAAAAAAAAAAA, which consists of a country code of “N” for Nauru, followed by the account number (up to 16–digits in length).

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 Nauru 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 Nauru through when establishing or changing IDD or use an SSA system (e.g., POS, MACADE). When using, bank data will post to the MBR within 4 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 (e.g., 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 4 business days of the current operating 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 IDD information.


To derive the 9-digit RTN for Nauru, code as follows:

  • prefix of 66 (the multi-country prefix SSA and FRBKC designated to use for IDD to Nauru),

  • 3 filler “000’s”,

  • 3-digit bank code based on FI name after verifying accuracy against either the help file or the listing in GN 02402.363H in this section, and

  • 1-digit check code, (obtained 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.


To code the DAN for Nauru, code as follows:

  • “N” designated for Nauru, and

  • account number (up to 16–digits in length).

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

F. Example of coding Nauru bank data

The customer provides us with a sign-up form for Nauru containing the following information:

  • Bank Code: 123, and

  • Account Number: 4567890123456789.

1. Derive the RTN as follows

  • prefix of “66” (the multi-country prefix for Nauru),

  • 3 filler zeros “000”,

  • 3-digit bank code “123” after verifying accuracy against either help file or the listing in GN 02402.363H in this section,

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

  • the type of account as a “C” for checking or an “S” for savings. If there is no indicated account type, use a “C” for checking.

2. Derive the DAN as follows

  • “N” (for Nauru), and

  • 16-digit account number 4567890123456789.

The coder will obtain the following:

RTN: 660001238


DAN: N4567890123456789

The coding in POS will reflect:






The MBR will reflect the following information:

RTN-660001238 DAN-N4567890123456789
