REVENUE MEMORANDUM CIRCULAR NO. 55-2004  issued on September 6, 2004 prescribes the BIR’s policy on the handling of TIN Verification queries raised by companies (i.e. credit card companies, telephone companies, etc.).
           TIN Verification inquiries of Companies shall henceforth be raised in writing via e-mail at contact_us@cctr.bir.gov.ph, by fax (at fax no. 981-7202) or by snail mail addressed to: Commissioner Guillermo L. Parayno, Jr., Attn: BIR Contact Center (BIRCC) Manager.
           In order for the BIRCC to process requests for TIN verification from Companies, heads of Companies should specify in writing the name and e-mail address of their designated representatives (at most two) who would be authorized to sign letter requests for TIN Verification for their agency. No formal designation of authorized representatives would mean no processing of requests for TIN Verification by Companies.
           TIN Verification inquiries by individuals, on the other hand, can still be raised via telephone (at 981-8888) and shall be responded to provided that the caller is able to supply correctly all the validation questions that will be asked by the BIRCC Agents.
