GoHighLevel Contacts Not Importing — Common Errors and Fixes

Why Contact Imports Fail

GoHighLevel contact imports fail silently or partially more often than they should. The import may complete with 0 contacts added, or import 60% of your list and skip the rest without explaining why. Here is how to diagnose and fix it.

Issue 1: CSV Column Headers Do Not Match GHL Fields

GoHighLevel maps import columns to CRM fields based on the header names. If your CSV has "Phone" but GHL expects "Phone Number", the mapping will fail or produce blank fields. During import, review the column mapping screen carefully and manually match each column to the correct GHL field.

Issue 2: Phone Numbers Are in the Wrong Format

GoHighLevel requires phone numbers without country code formatting issues. US numbers should be 10 digits (no spaces, dashes, or brackets) or in E.164 format (+1XXXXXXXXXX). Numbers in formats like (555) 123-4567 or 555-123-4567 will often fail or import incorrectly.

Before importing, do a find-and-replace in Excel or Google Sheets to standardise all phone numbers.

Issue 3: Duplicate Contacts

GoHighLevel deduplicates contacts based on email address. If your import file contains contacts that already exist in GHL with the same email, the import will skip them (not update them, just skip). You need to use the "Update" option if you want to merge data with existing contacts.

Issue 4: File Encoding Issues

Files exported from some systems (especially non-English systems) may have encoding issues that cause characters to display incorrectly or rows to fail entirely. Save your CSV file as UTF-8 encoded before importing into GoHighLevel.

Issue 5: File Size Too Large

Very large CSV files (over 10,000 contacts) should be split into smaller batches for import. Large imports sometimes time out or fail partially without clear error messages.

Issue 6: Required Fields Are Missing

GoHighLevel requires at minimum either an email address or a phone number for each contact. Rows with neither will be skipped. Review your import file and ensure every row has at least one of these.
