Frequently Asked Questions

No. If you’re already an EarthLink customer, we make it easy to transfer your service to your new address.

It only takes a few minutes to let us know you’re moving. We can help in two ways: check the available service for your new address above or call us at 888-327-8454.

For the smoothest transition, let us know you’re moving at least two weeks before you need service at your new address. It takes a little time, so the sooner you can let us know, the better. We ask for at least two weeks to avoid any downtime. We’ll keep you posted on progress via text on the phone number updated on your account.

An installation fee will be determined when your relocation order is submitted. Similar to the original installation, we’ll send a professional installer to get you all set up. Any early termination fees at the old address will be waived when service is established at the new address. Your new service will have an updated early termination fee.

Take your modem, power cord, and cables. When the technician arrives to set up your transferred service, they’ll take back what isn’t needed. Don’t be surprised if the technician provides new and better equipment.

You can upgrade at any time! We would have to check serviceability first to see what higher speeds are supported at your new address.

Not a problem! You can respond to the relocation confirmation text you receive from us or call as soon as you are aware that you need to make a change. The number is 888-327-8454 and select the “relocation” option if prompted. Please note: an adult (18 years or older) must be present at the new address at the time of installation.

We continue to widen our national internet service footprint, so this is getting more and more unlikely. However, if we can’t make this happen (we’ll miss you!), we will let you know right away so you can plan accordingly. Please note: any early termination fees will apply if the move occurs while the service is under contract.

Not a problem. We’ll need to talk to both of you together to transfer ownership of the service. Details we’ll need to collect name, email, phone, method of payment, and all security questions (which we will verify separately) to transition the account. Also remember: EarthLink email addresses can also be transferred.

We will make the arrangements to move your email address and any other service you have subscribed to.

*Actual speeds may vary based on network activity, configuration, and other factors. Subject to availability. Some prices shown may be introductory offers. Equipment fees, taxes, and other fees and restrictions may apply.
