letters after SS number

Submitted by Anonymous (not verified) on Tue, 12/27/2011 - 15:16

I am looking for what the letters after the claim number/social security number mean. I know that C1, C2, etc, means child and the SS number is actually a parents, but other letters, such as HA. Is there a list that can be printed out to know what each letter stands for?

Hi Deborah,

The Social Security claim number identifies whose account the client is drawing from and why they are receiving those benefits.
HA: Disabled claimant (wage earner)

Hi Nancy,
The letter refers to what relation you have to the person applying for disability benefits, "A" means that that person would be the primary applicant.

Hi Loanda,

HC1 is filed under a beneficiary identity code, however I would recommend speaking to a SSA representative.

HI Linda,
That's a social security beneficiary code. Generally, they describe what types of benefits you are eligible for. The awards letter should give you some detail about those benefits.

Hi Kahty,

The letter refers to what relation you have to the person applying for disability benefits, "A" means that that person would be the primary applicant.

"DI" is The claim number is the social security number under which a claim is filed or benefits are paid. If you are an SSI beneficiary, your claim number is your nine-digit Social Security Number (SSN) (000-00-0000) followed by two letters such as, "DI,"

Hi James,
I'm not sure what the "B" and the "DS" mean, but if your wife qualified for auxiliary benefits (payments in addition to yours) your monthly benefits will NOT be affects. These are just "extra" benefits because she's old enough to get assistance as well.

I have a SS letter with the claim number and then A and then below that is the same claim number with DI. I know that A means primary applicant and DI means under which the claim is filed or benefits are paid. What I don't understand is what benefit am I receiving SS benefits or SSI benefits or both?

I really could not say, but you may want to contact your banking institution for more information about how it processes and labels transactions in your account.

Hello. Why does my benefit verification letter have XXXX-XX-0000 DI, and below that my social security number XXXX-XX-1234 C1 below that? The lower set with XXXX-XX-1234 C1 is my social security number and I think the code for my SSI disability award. But I cant figure out what the top numbers and DI stand for. Thanks if you can help.

Hi Richard,
Those letter after those numbers are to indicate both which type of benefits you are receiving and a classification of who the beneficiary is.

Hi Rich,
Those numbers indicate information about your case and are used by the SSA to determine which beneficiary you are, in the case there are more than one beneficiary to a claim.

Social Security Number Codes

The codes following a Social Security number indicate the type of benefits you are entitled to. The Social Security number followed by one of these codes is often referred to as a claim number and they are only assigned once you apply for benefits. These letter codes may appear on correspondence that you receive from Social Security or on your Medicare card. They will never appear on a Social Security number card.

For example, if the Social Security of the wage earner number is 123-45-6789, then once you apply for retirement benefits; your claim number is 123-45-6789A. This number will also be used as your Medicare claim number, once you are eligible for Medicare.

A letter of explanation of determination is a letter sent from the SSA that explains why they came to decision of denying your claim.
