NOM 151 Overview
What is NOM 151?
NOM 151, or Normativa 151, is a Mexican standard that guarantees the integrity of electronic documents. It provides a data retention certificate that verifies the document hasn't been altered after signing, confirming its integrity and reliability for any transaction.
How does NOM 151 work?
Dropbox Sign integrates with eID Easy, a partner of Edicom, to support NOM 151 compliance for both Dropbox Sign web and API users in Mexico. This integration creates a secondary certificate, separate from the original signed document, that verifies its integrity according to NOM 151 regulations.
With the NOM 151 certificate enabled, signature requests will have this secondary certificate added to the request, which can be accessed through your Dropbox Sign account once the request is completed.
How can I add NOM 151 to my workflows?
Dropbox Sign users on a Premium plan can enable this feature through their Admin Console settings. Admins can navigate to their “Signature request options” settings to enable the NOM 151 certificate feature for their signature requests. Once enabled, the option to add a NOM 151 certificate will appear as an additional checkbox under the Signature Type options in the Dropbox Sign web workflow. Additionally, API users will be able to include thenom_151:true option in the certification_types parameter. Setup
Note: You must have a Dropbox Sign Premium plan to use NOM 151. Please see out our Dropbox Sign Pricing and our API Plans and Pricing page for more information.
