HAAD Is Now DOH, and the Portal Has Changed Too

For years, applicants registered directly through a HAAD-branded system. That’s gone. Everything, registration, DataFlow initiation, credentialing, and exam booking, now runs through TAMM, Abu Dhabi’s unified government services platform. If you’re following an old guide that tells you to “log in to HAAD,” stop and look for the Department of Health section on TAMM instead. The verification requirements themselves haven’t changed dramatically, but where you go to start the process has.

Throughout this article, “DOH” and “HAAD” refer to the same authority. You’ll still see both terms used interchangeably in casual conversation among healthcare professionals, and both are used here so this guide is useful regardless of which one you searched for.

What DOH DataFlow Actually Verifies

DOH DataFlow is the Primary Source Verification (PSV) that DataFlow Group performs on behalf of the Department of Health, confirming that your educational qualifications, professional license, and work experience are genuine by contacting the actual universities, licensing councils, and former employers that issued them, rather than simply accepting your submitted copies. No positive PSV report, no DOH license, full stop.

Step-by-Step: DOH DataFlow Process Through TAMM

1. Create your Unique Identification Number (UIN). Before anything else, you need a UIN, issued through the TAMM platform. Select “Department of Health” from the service menu, register as a new applicant, and choose your professional category (doctor, nurse, pharmacist, dentist, allied health, or technician). Without a UIN, you can’t move forward with DataFlow registration at all, and this is the one step that trips up applicants who are still following outdated HAAD-era instructions.

2. Register on the DataFlow portal using your UIN. Once your UIN is issued, use it to create your account directly with DataFlow Group and select DOH as your authority. As with every GCC health authority, DOH reports are authority-specific, so selecting the wrong one here means restarting later.

3. Upload your documents and complete PSV. DataFlow contacts your university, licensing council, and previous employers directly to confirm what you’ve submitted. This stage is the longest part of the entire process because it depends on third parties responding, not on DataFlow’s own speed.

4. Link your DataFlow case reference number to your DOH application. Once you receive a positive report, you don’t just move on. You have to actively link it. Enter your DataFlow case reference number into your TAMM/DOH application, which pulls your verified documents into the system DOH actually reviews.

5. Credentialing review. This is a step that’s genuinely distinct to DOH and doesn’t have an exact equivalent described clearly anywhere else. After your DataFlow report is linked, DOH staff run a separate “credentialing” review through the User Management System (UMS), checking your entire file against the Professional Qualification Requirements (PQR) for your specific title. This determines whether you’re actually eligible to sit the exam for the category you applied under. It’s not a rubber stamp, and candidates sometimes discover at this stage that their experience or qualifications place them in a different professional category than they expected.

6. Pay application and credentialing fees. These are paid through TAMM and are separate from your DataFlow verification fee.

7. Book and sit your exam. If your category requires it, you’ll book your licensing exam through Pearson VUE, accessible via TAMM once credentialing is complete.

Documents You’ll Need

• Passport copy and passport-size photograph
• Highest relevant qualification certificate and academic transcript
• Current professional license or registration
• Experience certificates covering your required clinical experience
• Good Standing Certificate (GSC), valid within six months of issue
• Any previous DataFlow reports from other authorities, if applicable

A detail worth flagging clearly: even though your documents get verified once through DataFlow, DOH’s own portal typically asks you to upload them again separately for its internal records, alongside your linked DataFlow case number. Don’t assume linking the case number alone is sufficient: check your application checklist on TAMM before submitting.

How Much Does DOH DataFlow Cost?

DataFlow’s fee for DOH verification typically falls somewhere between AED 1,100 and AED 1,400, depending on how many documents need checking. As with every authority, a base package usually covers your degree, license, Good Standing Certificate, and one experience letter, with additional documents (extra job history, postgraduate qualifications) billed on top individually. This is separate from the application and credentialing fees you’ll pay later through TAMM, so budget for both stages rather than treating DataFlow as your only cost.

Fee Breakdown at a Glance

Treat DataFlow’s fee as only one part of your total cost. Applicants who budget only for PSV are often caught off guard by the separate application and credentialing charges that follow on TAMM.

What a Negative or Discrepancy Report Means for DOH

A negative DataFlow report isn’t automatically the end of the road, but it’s serious. Discrepancy reports, where a university or former employer can’t confirm a detail exactly as submitted, are more common than outright fraud findings and sometimes can be resolved by submitting clarifying documentation. A confirmed negative report tied to falsified credentials, however, is recorded in the shared DataFlow system and becomes visible to other GCC authorities, not just DOH. This is one more reason to have every document, dates, spellings, job titles, checked carefully against your passport and official records before you submit anything for verification.

Tracking Your Application on TAMM

Once your documents are with DataFlow, check your status periodically through your TAMM account rather than assuming no news is good news. If a former employer or university hasn’t responded within a few weeks, a direct follow-up email from you, referencing your DataFlow case, often gets more traction than waiting for DataFlow to chase a second or third time on its own. Once you reach the credentialing stage, keep an eye on your UMS notifications specifically, since requests for clarification at that point tend to have a response deadline attached.

Realistic Timeline

Expect the DataFlow portion alone to take roughly one to two months from the date you submit a complete set of documents and make payment. That estimate assumes your university, council, and former employers respond promptly. An unresponsive former employer or a university with a slow international correspondence process can push this well past two months. Once your positive report is linked and credentialing begins, DOH’s own review is generally faster, but it still depends on how complete and consistent your uploaded file is.

Why the Credentialing Step Catches People Off Guard

Most guides treat DataFlow as the finish line. For DOH, it isn’t. A positive DataFlow report confirms your documents are genuine. It doesn’t automatically confirm you qualify for the specific professional title you applied under. The credentialing review against the PQR is where DOH makes that separate determination, and it’s entirely possible to pass PSV cleanly and still be asked for additional clarification, or be placed in a different professional category than the one you initially selected, if your qualifications and experience don’t map exactly onto your chosen title. Reading through the PQR criteria for your intended category before you even start your UIN registration can save you from an unwelcome surprise at this stage.

Which Professional Categories Need DOH DataFlow

DOH DataFlow applies broadly: general practitioners, specialists, dentists, nurses, pharmacists, and allied health professionals (physiotherapists, lab technicians, radiographers, dietitians, and similar roles) all go through the same PSV requirement before licensing. What changes between categories isn’t whether DataFlow is required, but which documents carry the most weight during credentialing. A specialist physician’s file, for example, gets checked against postgraduate qualifications and fellowship training far more closely than a general nurse’s file would be, which is part of why two applicants with a “positive” DataFlow report can still have very different credentialing timelines. Knowing your category’s specific PQR requirements before you submit anything helps you anticipate which document is likely to draw the closest scrutiny.
