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.
Notaries charge a modest fee for this service. Fees charged often depend on where you get a document notarized. Many states set maximum allowable charges, and notaries can charge any amount up to that maximum (and they can also charge nothing at all). In many cases, notarial charges are between $2 and $20 per signature.
