Just out of curiosity, did you provide your SSN.

While not required, it often eliminates questions of identity.

The NICS Section
Located at the FBI's Criminal Justice Information Services (CJIS) Division in Clarksburg, West Virginia, the NICS Section processes background checks for the FFLs in those states that have declined to serve as POCs for the NICS. The FFLs conducting business in these states will contact the NICS either by telephone, via one of two contracted call centers, or electronically by the NICS E-Check System via the Internet. When contacting the NICS by telephone, the FFL will provide the prospective After contacting the NICS, via two contracted call centers, either by telephone or electronically by the NICS E-Check System via the Internet, FFLs will provide the descriptive information provided on the ATF Form 4473, which is required by law to be completed and signed by every prospective firearm transferee. The prospective firearm transferee's descriptive information is required descriptive , the FFL will receive a response that the transfer may proceed or is delayed. This response is typically provided within 30 seconds.

If no matching records are returned by any of the databases, the transaction is automatically proceeded. If the NICS returns a match of the prospective firearm transferee's descriptive information to that of record information located in any of the databases, the FFL is advised that the transaction is delayed. While the FFL is still on the telephone, the call is placed on hold and transferred to the NICS Section in Clarksburg, West Virginia, for a quick review and evaluation by an FBI NICS Legal Instruments Examiner (NICS Examiner). If the record information returned by the NICS presents a valid match to the descriptive information of the prospective firearm transferee, the NICS Examiners, who have access to protected information (as opposed to Call Center personnel who do not have such access) reviews the information if state and federal firearm prohibitive criteria exists. If the information matched by the NICS is not a valid match or no prohibitive criteria exists, the FBI NICS Examiner will advise the FFL to PROCEED with the firearm transaction. The FFL must record the NICS Transaction Number (NTN) on the ATF Form 4473 and retain the form for auditing purposes.

If it is determined that prohibitive criteria exists, the FBI NICS Examiner will advise the FFL to DENY the firearm transaction. If potentially prohibitive criteria exists and more information is required in order to make the determination, the NICS Examiner will advise the FFL to DELAY the firearm transaction and the call is concluded. The FFL must record the NTN on the ATF Form 4473 and retain the form for auditing purposes.

When a transaction is DELAYED, the FBI NICS Examiner begins extensive research on the potential prohibitor. When the research is complete, the FBI NICS Examiner calls the FFL and gives a PROCEED or DENY decision on the firearm transaction.

On the third business day of a DELAYED transaction, the NICS Examiner is required to call the FFL and advise him/her of their rights under the Brady Act to transfer the firearm after the third business day. If the delayed transaction cannot be resolved within the allowed three business days, it is at the discretion of the FFL whether to allow the firearm transfer. However, the NICS Section continues to research the case in an effort to obtain complete disposition information. Business days do not include the day the check was initiated Saturdays, Sundays, and any day state offices in the state of purchase are closed.
