The IRS assigned POP Protocol an Employer Identification Number (EIN) of 81-2402073. POP Protocol must use this EIN and its complete name and address exactly as shown when filing taxes, payments, and correspondence. While POP Protocol indicated it is non-profit, being assigned an EIN does not grant tax-exempt status - it must apply using Form 1023 or 1024. POP Protocol also likely needs to file a Form 990 to maintain tax-exempt status if it qualifies.
