# Why is my Vercel Deployment URL being shortened? **Author:** Matthew Sweeney, Mary Karroqe --- Vercel provides automatic [Deployment URLs](https://vercel.com/docs/deployments/generated-urls) that allow you to share a live version of the changes you've made and collaborate with your team. The format of Deployment URLs is consistent and predictable dependent on the [Deployment Type](https://vercel.com/docs/deployments/overview#deployment-types). This article covers the case where a Deployment URL would be shortened and explains the reason for this. ## RFC 1035 [RFC 1035](https://tools.ietf.org/html/rfc1035) mandates that the maximum length of a DNS label is 63 characters. As a result, if the automatically generated Deployment URL exceeds this length, it will be trimmed from the end of the URL to fall within this limitation. Where team slugs are used as part of the Deployment URL, the entire team slug will be trimmed if any amendments need to be made. ## Anti-Phishing Protection If your `` resembles a regular web domain, such as by containing a recognized top-level domain (TLD), it may be shortened to avoid that resemblance. For example, `www-company-com` would be changed to just `company`. This is done to prevent an accidental trigger of anti-phishing protection built into web browsers that protect the user from visiting domains that look roughly like other domains they visit. --- [View full KB sitemap](/kb/sitemap.md)
