Instructions for Submitting Applications via Email

The Portable Equipment Registration Program (PERP) accepts all registration applications and reports via email at: [email protected]. Follow the instructions below to ensure prompt application processing; failure to follow the instructions will result in delays.

• All applications require current forms downloaded from the Application Forms webpage.  Forms are updated periodically. Ensure you have the most up-to-date forms to prevent any delays in application processing by downloading current forms.
• Submit only one company account per email. This will ensure equipment is registered to the correct account. Accounts are based on both mailing and street addresses. If you have multiple accounts or are unsure, please contact [email protected]. 
• Include Form 1 with Form Numbers 2 to 15. A Form 1 is required per email to ensure the company information is up to date and equipment is registered to the correct account.
• There will be a limit of five (5) units with supporting documentation per emailed request. This limit avoids size-related undeliverable emails.
• If submitting multiple units, all units must be the same unit type. Each form number is a different unit type. If unsure of which form to use, please contact [email protected].
• Rename forms and supporting documentation by the form number and serial number listed on the form. This will allow PERP staff to organize and combine your application quickly and accurately, especially if submitting multiple units.
  • Examples:
    • Form 1: Form 1_Company Name
    • Form 2: Form 2_Serial Number
    • Photos: Form 2_Serial Number_Photo1 and Form 2_Serial Number_Photo2
    • Documentation: Form 2_Serial Number_Doc1 and Form 2_Serial Number_Doc2
• Email completed and signed application forms and associated photos, documents, flow diagrams, and compliance reports to: [email protected].

Note: For registrations being renewed, you may submit modification, correction, placard replacement, and/or company update forms with your renewal invoice to: [email protected]. This will ensure processing of both requests at the same time.

When PERP receives your application,you will receive a response within 30 days. Please contact PERP staff at [email protected] if you do not receive a billing invoice or staff follow-up within 30 days. Per the PERP Regulation, PERP has 90 days to issue registration once the application is deemed complete and registration fees are paid.
