Express Written Consent - What It Is, How To Obtain It And Some Examples

Expressed written consent (EWC) is permission for something that is given specifically in writing. Learn how to obtain EWC from your contacts for automated calling and mass texting communications.

Sigma Voice is a service provider of automated calling and mass texting.

What is Expressed Written Consent?

EWC is clearly defined in the Telephone Consumer Protection Act 47 U.S.C. § 227. It is required prior to receiving automated phone calls or text messages. Essentially, your contacts must agree to receive communications from your organization.

In addition to actual handwritten consent, it may also be obtained from an email message, text message or an web form.

How to obtain Expressed Written Consent

There are several ways to ensure you've obtained EWC.

Email Message

Text Message

Web Form

Expressed Written Consent Examples

Below are a few examples from websites you may be familiar with.

I consent to receiving telemarketing calls or texts at this number using an automatic telephone dialing system by, or on behalf of, Hyundai and its authorized dealers. I understand I do not have to consent in order to purchase any products or services. Carrier charges may apply.

Mobile Consent Agreement*
I agree to receive future calls on my mobile number from AAA (or on
AAA's behalf) regarding my membership or insurance, including renewal
reminders, and other offers. These calls may use an automatic
telephone dialing system, a prerecorded voice message, or text
message. Providing my consent is not a condition to the purchase of
any AAA good or service.
