Why Do JAMB Keep telling me That my email is invalid?

There are two major reasons why you may get this error (Invalid email format) each time you try linking your Email address to JAMB online profile, these reasons are;

  1. The context of the message you sent to 55019 did not follow the specified format by JAMB
  2. The Email you are trying to link to JAMB was not what you registered JAMB with.

I will explain each of these two possible causes, and how you can find your way around them, keep reading diligently for details…

1. SMS was not formatted Properly

Some students, when they try linking their email to JAMB, the way they format the text message does not correspond with JAMB recommendation, and this can make the entire process not successful.

If you want the linking to be successful, the SMS you send must follow the right pattern as shown in the image above…

…to make this easy for you, I have prepared the text format here in this post, all you have to do now is copy the text I will provide you with shortly and paste it on your SMS app.

[email protected] 
[email protected]

Copy the text above and paste on your text app, then edit the email replacing it without your correct email address.

Mind You: This email address must be what you registered JAMB with

This brings me to the next possible cause…

JAMB made email not a compulsory requirement for JAMB registration, and as such, some JAMB registration centers did not bother asking students for their Email address when they were been registered.

These set of students (those their email address were not registered with JAMB during registration) cannot use the normal SMS method to link their Email address to JAMB, if they must link their email address they will have to follow the procedures below…

But how do I know if I registered JAMB with my email address already?????

Good question, you can tell if you registered JAMB with your email address simply by checking your JAMB registration slip, on the slip, under PERSONAL DETAILS, you will find something like this…

Surname: *******
First Name: ******
Other Name: ******
Date of Birth: ******
Physically Challenged: ******
Gender: ******
GSM No./eMail: ******

At the last information “GSM No./eMail” check to see if your Email address was clearly stated, if the space for email is empty, then you did not register with JAMB but if it shows an email address, that is the email address you are to link to JAMB.

With these piece of information, am confident you won’t have a hard time trying to link your email address to JAMB.

In Conclusion

You will mostly get the Invalid email Format feedback error each time you try to link your email address through 55019 when the email address you are trying to link is not what you registered JAMB with or when you did not register JAMB with any email address at all.

  1. I used last year email to register for this year’s jamb
    They already sent me the password the day I registered
    I tried logging in to jamb portal , but it was showing invalid email or password
    What can I do?

    1. You should be able to access your JAMB CAPS using that email and password, ensure you entered the correct email and Password using the right case (capital or small letters)

  2. Sir, i already used the same email last year for this year and can’t see the current result in my portal what do I do to change the email? or what do I do entirely?

  4. I tried what u said but it did not work
    The Same email on the GSM No/email I tried it but still not working I don’t know what to do please

  5. I’ve been trying to create a JAMB CAPS account but it kept saying this. And the phone number I used for registration is the same one I used here. How do I go about this please?

    1. Hey Halima, apparently you tried using the old method for creating your JMB profile, that is why you get that error.

      To create your JAMB profile now, you will have to do so by linking your email address to JAMB, once this is done, you will be sent your USERname and PASSword, which you can then use to sign into your JAMB account.

      Mind you, this linking of email to JAMB can only be done currently at any JAMB approved CBT center closest to you.

      1. It worked!
        I’d already linked my email and had been sent the password exactly a month ago! I honestly didn’t know that’s the password I’m going to use.
        Thank you so much DrugSavant, I really appreciate it. How could I ever repay you ????
        Thank you once again.

    1. Hey Sulaimon, currently you can’t link your Email to JAMB using SMS, it can only be done at an accredited JAMB CBT Center.

      Visit JAMB CBT center closest to you to get this done for you.

  6. During jamb registration
    Under personal details
    In the place of GSM No./e-mail my phone number was their
    And that what i have in my registration slip and i can’t login to jamb portal
    Please can i do?

    1. This means you are yet to link your email address to JAMB.

      Proceed to any jamb CBT center to get your email linked, only then will you be able to access your jamb profile with the password sent to you.

  7. I uploaded my O level results on JAMB portal yesterday and I decided to confirm today by checking CAPS but it keeps telling me “you are not eligible to use this service” and I crossed checked by making sure I inserted the correct reg. no & year registered but it keeps telling me the same thing. Pls what should I do?
