Market Size for Notary service in 2026 [Example]

The total available market (TAM) for notary services globally can be estimated by analyzing the number of transactions requiring notarization. In the U.S. alone, approximately 4 million notary transactions occur annually, with an average fee of $75 per transaction, leading to a TAM of roughly $300 million in the U.S. If we estimate similar demand across other developed nations with 5x the population, we can project an approximate global TAM of $7.1 billion.

This assumes that each transaction corresponds to a unique instance of notarization, leveraging regulated sectors like real estate, legal, and financial services where notarizations are necessary.

The serviceable addressable market (SAM) is realistically the portion of TAM that your notary service can reach. Given that you might focus on digital solutions and specific markets, we can estimate capturing 20% of the TAM, leading to an SAM of approximately $1.42 billion.

This figure accounts for geographical limitations and niche service focus which mainly target urban centers or specific legal and business communities that require notarization regularly, allowing for a realistic capture.

The serviceable obtainable market (SOM) is the slice of the SAM that you can realistically capture in your first year of operation. Capturing 1% of your SAM would result in about $14,200 in revenue, assuming typical engagement levels.

In terms of customer base, this amounts to roughly 280 customers. This conservative estimate reflects the hurdles faced by new entrants in acquiring customers in established markets, making it a manageable target within your first year.
