How can I change the default URL in my Shopify admin?

Topic summary

Issue: Merchant wants the Shopify admin URL to reflect their brand (e.g., saffiastore.myshopify.com) instead of the auto‑assigned subdomain (ac3cb8.myshopify.com).

Official guidance: The myshopify.com subdomain assigned at signup is permanent and cannot be changed or removed. It’s used internally for admin access, sign-in, and support; customers see the custom domain (e.g., saffiastore.com) on the storefront.

Implications: Changing the store name or connecting a custom domain does not alter the original myshopify.com URL. The custom domain controls what customers see publicly, not the internal admin URL.

New development: Another merchant reports an “order status” notice indicating use of a default URL and is prompted to change it in Domains but cannot. They ask how to have their purchased domain appear in checkout or other personalized areas instead of random characters.

Status: The original question is resolved (cannot change ac3cb8.myshopify.com). The follow-up question about checkout/order status domain behavior remains unanswered in this thread.

Hi @Saffia_Store ,

Thank you for reaching out to the Community! I’m happy to provide some assistance with domains, to ensure this gets resolved.

To share some insight, your online shop was given a myshopify.com URL when you first signed up for Shopify. This URL has a few different functions that are necessary to keep your online shop running smoothly. By default, this web address is where customers go to find your online shop but can be changed by purchasing a custom domain. For more information on this, you can check out our Domains Documentation as it touches on this further.

As you have successfully purchased and connected a custom domain, customers will see saffiastore.com when browsing your online shop. The myshopify.com URL however, will remain internally as it’s used for accessing Support and Signing In to your shop. While I can completely understand how this may not be ideal, the myshopify.com URL is unable to be completely removed from the shop.

Please let me know if you have any other questions or concerns.
