An Adoption Taxpayer Identification Number (ATIN) is a temporary nine-digit number issued by the IRS to individuals who are in the process of legally adopting a U.S. citizen or resident child but who cannot get an SSN for that child in time to file their tax return.
How much is it? On average, a notary is going to anywhere from $0 to as much as $10. Public companies, such as FEDEx Kinkos and the UPS Store, usually charge around $5 to $10 to have a single-page document notarized. For example, SFBayNotary.com charges $5 per every notarized signature.
The document must be either notarized by a DC notary public or signed by an authorized head of a DC government agency. The Office of Notary Commissions and Authentications does not notarize documents. The cost is $15 per document, payable by check, money order or Visa or Master Card.
