Generating a GUID/UUID on your deliveries


A UUID (Universally Unique Identifier) or a GUID (Globally Unique Identifier) are unique identifiers which your buyer's CRM may require to ensure a successful delivery.


The most commonly found format is RFC 4122 and this is 5 groups of hexadecimal digits separated by hyphens, the length of each group being: 8-4-4-4-12.

EG: 123e4567-e89b-12d3-a456-426655440000


We can generate a GUID/UUID on LeadByte delivery output through the use of the [GUID] tag:

In delivery URL -



In the delivery body -



After adding the [GUID] tag, you'll be able to alter how your GUID is generated through the settings found within the "options" button:



Lead based will generate the GUID utilising your Lead ID as the source.

RFC 4122 will follow the most commonly used format, detailed at the top of the article.

Custom uses our "smarty tag" functionality to generate a GUID. Unless you're a developer, you will probably need help with this option!
