An apostille isn't a notary stamp — it's a separate state-level authentication (from the Secretary of State or a state Department of State office) that most mobile notaries don't handle, and no map filter can tell you which ones do. Every listing here has apostille service confirmed straight from the notary's own website, rate sheet, or booking page.

Good to know
How much does an apostille cost?
Mobile notaries typically charge $75-$150 for full apostille processing (their service fee plus the state's $15-$20 filing fee and courier costs), on top of a $15-$50 mobile notarization fee for the signature itself. Doing it yourself through the Secretary of State by mail costs less but usually takes 2-4 weeks; a notary who runs the paperwork in person can often turn it around in 1-3 business days.
How long does it take to get an apostille?
Walk-in or courier-assisted apostille service through a mobile notary usually takes 1-5 business days depending on the state, versus 2-6 weeks if you mail the document to the Secretary of State yourself. States like Texas, Florida, and California offer same-day or next-day apostille windows that notary services regularly use for rush orders.
