Connect your WhatsApp number

Setup guide · Updated September 2026

You connect your own number to Esek through Meta's own signup window. We open it, Meta runs it, and the number comes back to us at the end.

The walkthrough below is short. Most of this page is the part after it, because almost everything that goes wrong here goes wrong inside Meta's window, where the message on screen rarely says what to do next.

Before you start

No spare line? Which lines work and where to buy one.

The walkthrough

The pictures below are from Meta's own walkthrough of this window, so the sample partner in them is called Zoomture and the sample business Wind & Wool. On your screen those two read Esek and your own business name. Everything else is the same.
  1. Open esek.io in a browser and sign in. Go to Go live, or Settings then WhatsApp.
  2. Press Connect WhatsApp. A Meta window opens in front of the page.
  3. Log in to Facebook. Pick a Business portfolio, or create one when Meta offers.
    Meta's window asking to continue with the signed-in Facebook account.
    Step 3. Meta asks which Facebook account to continue with.
  4. Pick the phone number, or add it. Meta sends a code to it by SMS or by call. Enter the code.
    The number entered, with a choice between a text message and a phone call.
    Step 4. The number, then a text message or a phone call.
  5. On the last screen press Finish. Wait for the window to close by itself and for Esek to say the number is connected.
    The last screen of Meta's window, with the Finish button at the bottom right.
    Step 5. Finish sits at the bottom right.
Leave the last screen through Finish and nothing else. Which buttons appear there depends on the account, and some of them are exits. Anything except Finish ends the run with the account made and the number not registered, and Esek will still say nothing is connected.

When it goes wrong

Find the sentence closest to what you are seeing.

"There is no Connect button in the app on my phone."

There is not one. Meta's login cannot run inside the phone apps, so connecting is a web-app job.

Fix. Open esek.io in a browser, sign in, and connect there. The phone app works normally once the number is connected.

"I pressed Connect and nothing happened."

Meta's window is a browser popup, and your browser blocked it. All you get is a small icon at the right end of the address bar, a window with a line struck through it. No message, no sound, nothing on the page.

esek.io this one
Chrome 152. The icon carries no words next to it, which is why it gets missed.

Fix. Allow popups for esek.io, then press Connect again. If that does not help, an ad blocker or privacy extension is the next suspect. Turn it off for esek.io, or try a private window with extensions disabled.

"Meta says the number is still on the WhatsApp app."

There is a WhatsApp account on that number, personal or the WhatsApp Business app. Meta will not take it until that account is gone.

Fix. On the phone holding the number, open WhatsApp, then Settings, then Account, then Delete my account. Then connect again. Deleting takes the chats and groups on that number with it and cannot be undone. If you are not willing to lose them, connect a different line instead.

"Meta says the number is already used by another WhatsApp Business account."

The number is already sitting on a WhatsApp Business account somewhere in Meta. An old agency, a previous provider, or an earlier attempt of your own.

Fix. Open Meta Business Manager with the account that owns it, find the WhatsApp account holding the number, and remove the number from it. Then connect again. If nobody can get into that account, only Meta support can release it, and using a different line is usually faster.

"Esek says this number is already linked to another business."

Different problem, same words. This one is ours, not Meta's. The number finished the Meta side, and another Esek workspace already holds it.

Fix. You almost certainly have a second Esek workspace, often from an earlier signup with a different email or phone. Sign in to that one and use it, or write to us and we will move the number.

"Meta wants a Business portfolio and I do not have one."

Normal. A Business portfolio is Meta's container for a business, and most merchants have never made one.

Fix. Create one inside the window. Use the legal business name and a business email address. It does not have to match anything you already have on Facebook. One portfolio is enough, so do not make a second one on a later attempt.

The asset step, with a Business portfolio dropdown above WhatsApp account, Facebook Page and Ad account.
The portfolio sits above the other assets. Meta creates the rest.

"The portfolio I want is greyed out and I cannot select it."

Meta greys portfolios out in that picker and gives no reason on screen.

Fix. Pick another portfolio, or create a new one, and carry on. Then tell us which portfolio was greyed out. That case needs a manual setup from our side and there is nothing you can do about it inside the window.

"I think I picked the wrong portfolio."

It shows up at the end, not during. Either the number that comes back is not the one you meant, or Esek refuses the connection outright.

Fix. Press Connect again and pick the portfolio that owns the number. Nothing is lost by running it a second time, and Esek refuses a mismatch rather than quietly repointing your workspace at the wrong number.

"Meta is asking for a six-digit PIN and I never set one."

That is two-step verification on the number. Esek sets and keeps that PIN for the numbers it registers, so you are never asked to invent one. Meta asks only when the number already had two-step verification switched on from an earlier setup, and it will not accept a different PIN.

Fix. Turn two-step verification off for that number in Meta's WhatsApp Manager, then connect again. If you cannot get into the account that holds it, write to us with the number before you try again, because repeated wrong PINs get the number locked for a while.

"Meta is asking me to verify my business."

Business verification is Meta asking for documents about the company. It is a separate process and it is not part of connecting a number.

Fix. Skip it and finish the connection. You can come back to it. It raises how many people you may message and unlocks some Meta products, so it is worth doing later. Talk to us before you submit anything, because the details have to match your company registration exactly and a rejected submission is slow to undo.

"Meta said it finished, but Esek says nothing is connected."

The run ended on the last screen without registering the number. The usual cause is leaving that screen through the payment-method button instead of Finish.

Fix. Press Connect again and go through to Finish. Nothing is lost, nothing is charged twice, and the account Meta already made is reused.

"The Meta window is just sitting there."

It stopped talking to us. It will not close itself and it will not finish.

Fix. Close the Meta window, then press Connect again. If the number was created only minutes ago, give it a few minutes first. Meta needs time to publish a new number across its systems, and connecting inside that window fails for a reason that clears on its own.

"Esek says I need a plan, a card, or activation before the number goes live."

A real refusal, and it arrives late by design, after Meta's window has already run. From where you sit the whole thing looks like it failed. It did not.

Fix. Settle whichever one it asked for, then press Connect again. Nothing you have set up is lost. Adding a card is not a charge.

"I connected the number I sign in with."

That number is now off the regular WhatsApp app, so your Esek sign-in code has nowhere to arrive. You stay signed in on this device, so nothing breaks today. The next sign-out is the problem.

Fix. Do this now, while you are still signed in. In your account, move your sign-in to another number you still use in the regular WhatsApp app. If you have none, put the email address of your Google or Apple account on your Esek account and sign in with that account next time. The address on its own is not a way in, and a different address opens a new, empty account.

Once it is connected

On forwarding codes. The short code you dial depends on the carrier. Vodafone in the UK is the one we have confirmed against the carrier's own published page. Every other carrier gets the standard code, which normally works but which we have not confirmed with them. If the code is refused, ask the carrier to set forwarding on unanswered calls for you.

Still stuck? Message us on WhatsApp from any page on esek.io, or email info@esek.io. Send the number and a photo of what is on screen. If a setup call would be easier, ask for one.
