CAQH Provider Data Portal Setup Guide 2026: Register, Complete, Authorize and Attest

By Cactus Billing Solutions, Tempe, AZ · Updated October 2026

If you have applied to almost any commercial insurance company, you have been asked for your CAQH ID. The CAQH Provider Data Portal (formerly CAQH ProView) is the online profile insurers use to read your credentialing information. Instead of filling out a long application for every payer, you enter your details once, keep them current, and authorize each plan to view them. A missing, incomplete or expired CAQH profile is one of the most common reasons credentialing stalls, so it pays to set it up correctly.

A quick note on the new name

CAQH now operates as DataSpring, powered by CAQH, and ProView is now called the CAQH Provider Data Portal. According to DataSpring’s clinician page, nothing changes for providers: your login, profile, documents and saved links stay the same, and the portal is free for clinicians and practices. You will still sign in at proview.caqh.org, and some insurers still say “CAQH ProView”, but we use the official name, CAQH Provider Data Portal, or simply “CAQH”.

Before you start: gather your documents

The profile asks for a lot of detail. Having it ready turns a multi-day project into an afternoon:

• Your individual NPI (and group NPI and tax ID if you bill through a group).
• State license(s) with numbers, issue and expiration dates.
• DEA and state controlled-substance registrations, if applicable.
• Board certification details, if applicable.
• Malpractice insurance certificate (face sheet) showing carrier, policy number, dates and limits, plus your claims history if any.
• Education and training: schools, residency or fellowship, with dates.
• Work history with month and year for each position. Many plans want an explanation for gaps. AZ Blue, for example, asks about any gap over 12 months in the last five years.
• Practice locations: addresses, phone, hours, and whether you accept new patients.
• Hospital affiliations or admitting arrangements, and a W-9.
• A current CV to check dates against.

Step 1: Register and get your CAQH ID

There are two ways in. If an insurer has already added you, you will get a welcome email with a link and your CAQH Provider ID. If not, you can self-register at proview.caqh.org/pr. Use an email address you will keep long term, because attestation reminders and plan requests go there. Write down your CAQH ID; every payer application will ask for it.

Step 2: Complete every section of the profile

The CAQH provider user guide sums up the process in six steps: register, complete all application questions, review your profile for accuracy, authorize organizations to access it, attest, and upload supporting documents. Work through each section: personal information, professional IDs, education, specialties, practice locations, hospital affiliations, insurance, work history and the disclosure questions.

Tips that save time later:

• Match your other records exactly. Use the same legal name, practice address and tax ID that appear on NPPES, your license and your W-9. Mismatches trigger follow-up questions from payers.
• Answer disclosure questions carefully. If you answer “yes” to any question, give a clear written explanation. A short, honest explanation is better than a vague one.
• Mark practice locations accurately, including telehealth and whether you are accepting new patients. Plans use this data for their provider directories.

Step 3: Upload supporting documents

Use the Documents page to upload items such as your license, DEA certificate, malpractice face sheet, board certificate, W-9 and CV. The CAQH quick reference guide notes that the Documents or Review pages tell you which documents are still needed. Upload clear, current copies. An expired certificate sitting in your profile is a common reason payers send your file back.

Step 4: Authorize the insurance companies

This is the step people forget. Insurers can only see your profile if you authorize them. You can allow all participating health plans, or pick specific plans. If you choose specific plans, remember to add each new insurer before you apply to it. Some payers, including AZ Blue, will reject a credentialing request if their access to your CAQH profile is missing or has expired.

Step 5: Review and attest

When everything is entered, select Attest, click Review to see a summary, fix anything that’s wrong, and then attest that your information is true, correct and complete. Your profile status moves from “Profile Data Submitted” to “Initial Profile Complete” once your required documents are accepted. Only then do authorized plans see a complete profile. CAQH also points out that after attesting, you still need to check with each organization for your credentialing status, because CAQH doesn’t credential you; the insurers do.

Step 6: Re-attest every 120 days

CAQH requires you to re-attest at least every 120 days (every 180 days for providers practicing in Illinois), even if nothing has changed. If you miss it, your profile shows as Expired Attestation, and plans may stop processing your applications or recredentialing. Some plans also ask providers to confirm directory details (name, specialty, address and phone) more often, every 90 days. When you renew your license, DEA or malpractice policy, upload the new document and re-attest right away rather than waiting for the reminder.

CAQH checklist

• CAQH ID recorded and shared with your credentialing contact.
• All sections complete, with no gaps in work history left unexplained.
• Current documents uploaded, with no expired certificates.
• Every insurer you are applying to is authorized.
• Attested within the last 120 days, with a calendar reminder for the next one.
