Imperigo is a research platform for publicly filed IRS Form 990 nonprofit data, operated by Imperigo at imperigo.com.

Account holders may optionally enable two-factor authentication on their account. One of the available methods is SMS: a one-time numeric security code sent by text message to a mobile number the user provides.

This messaging program sends transactional security codes only. Imperigo does not send marketing, promotional, or informational SMS messages of any kind.

Opt-in happens inside a registered Imperigo account. There is no other way to be enrolled in this program. Numbers are never imported, purchased, or added on a user's behalf.

  1. The user creates an account at imperigo.com and verifies their email address.
  2. The user is shown the two-factor authentication setup screen, where SMS is one of three options alongside an authenticator app and email codes.
  3. The user selects SMS text, enters their own mobile number, and checks the consent box shown below.
  4. A confirmation code is sent to that number and must be entered to complete enrollment.

Users may also enable, change, or disable SMS two-factor authentication at any time from Account → Security.

The image below shows the actual enrollment screen presented to users, with the SMS option selected, the mobile number field, and the consent checkbox.

This is the exact text displayed beside the consent checkbox on the enrollment screen. The box is unchecked by default and must be actively checked by the user before enrollment can proceed.

By checking this box, you agree to receive automated one-time security code text messages from Imperigo at the number provided. Consent is not a condition of purchase — authenticator app and email verification are available as alternatives. Message frequency varies based on account activity, typically one message per login attempt. Message & data rates may apply. Reply STOP to opt out or HELP for help.

Each opt-in is recorded with a timestamp, the mobile number provided, the IP address of the request, and the exact consent text shown at the time.

Every message sent under this program follows the same format. Messages contain no links and no promotional content.

Reply STOP to any message to unsubscribe immediately. You may also reply STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT.
