The Field Matching service allows you to confirm your customers’ identity, confirm account ownership, or verify the accuracy of the information before connecting a customer’s bank account to your financial service.

The /FieldMatch API responds by providing a match rate, along with the data points on the account that the customer is attempting to connect. The match rate refers to how closely the customer information that you pass using /FieldMatch resembles the data points on the account.

Refer to the table below for a description of each match score range. For examples of what this can look like in real life, see Matching Examples.

Range	Description	When to use
1	Exact Match	The data points are an exact match and the fields contain identical customer information.
0.80-0.99	Strong Match	There may be some spelling errors, nicknames, abbreviations, or missing characters in the data fields, but the information is a very close match.
0.65-0.79	Possible Match	There may be aliases or missing information, but the data points have some similarities.
0.50-0.64	Unlikely match	The accounts have similar information, such as a last name or postal code, but most likely do not belong to the same person
0-0.49	Very Unlikely Match	The information has no common factors.
