Why You Might Not Receive a Text

Poor Network Connectivity

Sometimes, a weak or intermittent connection can prevent the code from coming through. Make sure you’re in an area with good signal strength, or try switching to a different network (Wi-Fi or mobile data).

Mobile Carrier Delays/Outages

  • Mobile carriers occasionally experience delays or service disruptions that can affect the delivery of messages, including verification codes. If possible, check with your carrier for any ongoing issues.

  • Some international carriers may not support SMS verification in every country. We recommend signing in using an alternative option instead!

Spam Filters

  • Sometimes, your mobile carrier or phone settings may mistakenly flag a verification message as spam. Try checking your junk folder and reviewing your message filtering settings!

  • If you've previously unsubscribed from SMS texts, you may no longer be able to receive verification codes. (If that's the case, we recommend requesting an emailed code instead.)

Phone Number Already in Use

If you try to use a phone number that is already associated with another Donor Profile, you might not receive a verification code.


Why You Might Not Receive an Email

Delivery Issues

You may not receive an email if your email address is invalid, blocked by your email provider, or if you previously unsubscribed from Overflow emails.

  • Double-check that your email has a valid domain and is free of typos.

  • We recommend reaching out to your email provider for further assistance.

Email Delays

Sometimes, email providers may temporarily slow down or delay emails coming from the same sender if multiple messages are sent within a short time frame.

  • This is a common security step to help protect your inbox from spam.

  • Because of this, subsequent emails sent soon after the first may take a little longer to arrive.


Alternative Options

Emailed Verification Code

As an alternative, you can request to have the verification code sent to your email address. This can often bypass the issues experienced with SMS delivery.

Sign in with Google

You can also sign in using your Google account. This can be a quicker and easier option to verify your identity, especially if you’re a first-time donor or if your Donor Profile is already linked to your Google email address.
