This document contains current content limits and rate quotas for
reCAPTCHA. This page will be updated to reflect any changes to these
restrictions and usage limits.
Rate quotas
The current API usage quotas are as follows (and are subject to change):
Quota
Value
Requests per calendar month (if billing is not enabled)
10000
Requests per minute
60000
MFA Requests via email per email address per day
10
MFA Requests via SMS per phone number per day
10
MFA Requests via SMS per phone number per 4 hours
5
MFA Requests (email/SMS) per day
10000
These limits apply to each Google Cloud console project and are shared across
all applications and IP addresses using that project.
When you reach a quota limit
When your API usage quotas exceed the specified quotas limit,
any new request returns an HTTP error with a Resource Exhausted (429) status
code.
For V2, an end-user-visible error message is shown similar to the following
message: This site is exceeding reCAPTCHA quota.
What to do if you expect to go over the quotas
To use reCAPTCHA above the monthly free quota,
enable billing
for your Google Cloud project. The monthly assessment quota is reset on the
first day of each month.
If you expect to exceed other quotas, reach out to your assigned Google Cloud sale
point of contact. If you do not have an assigned Google Cloud sale point of
contact, contact Google Cloud sales.
