Create a custom URL field on any standard or custom object so a record can link to an external web address. You need permission to customize the object, usually the Customize Application permission.
- Open the object in Object Manager
In Setup, go to Object Manager, pick the object (for example Account), then open Fields and Relationships and click New.
- Choose the URL data type
On the data type step, select URL, then click Next. This is what makes the value render as a clickable link instead of plain text.
- Name and describe the field
Enter a Field Label, let the API name fill in, and add help text so users know what address belongs here. Click Next.
- Set visibility and add to layouts
Choose which profiles can see or edit the field with field-level security, confirm the page layouts to add it to, then click Save.
Must be set to URL so the value displays as a hyperlink and is capped at 255 characters.
The human-readable name shown on the page layout, for example Partner Portal or Website.
The unique developer name used in formulas, Apex, SOQL, and the API; auto-suggested from the label.
- The value is limited to 255 characters; longer links need a Long Text Area plus a HYPERLINK formula or a child record.
- Salesforce does not check that the link works or that the destination is safe, so add a validation rule if you need to enforce https:// or block bad domains.
- Addresses entered without a protocol may show an http:// prefix in reports because Salesforce prepends it on display.
