Verify an ISA Certification - By Postal Code
Verify a Certified Arborist Main Menu
HOW TO USE THE SEARCH OPTIONS: This is a method for verifying someone is an ISA certification holder by Postal Code. The search is not case-sensitive. Searching by zip/postal code may result in a broader result than searching by city and/or state. Searching by city and/or state only returns results that exactly match your criteria. Searching by United States zip code will return at least 30 records, looking outside the target zip/postal code you entered if necessary. Searching by a non-United States Postal code will only return records for that exact Postal Code. PLEASE NOTE! If the person you are searching for has moved and has not notified ISA or updated the information in our search database, you may not get search results.
By using the ISA Verify a Certified Arborist utility you are agreeing to the following terms and conditions.
If you are a certified arborist and have a ISA username and password you may update your information in the Verify A Certified Arborist database by clicking here.
