This free Irish HLR lookup shows whether an Irish mobile number is active.
An HLR lookup asks a mobile number's own network whether the SIM is switched on and reachable. Enter an Irish mobile number above, with Ireland already selected, and 1Lookup's free tool returns its status, its country and whether it was ported, without sending an SMS. It needs no signup.
Pick the country, then enter the number without the country code.
Free & rate-limited. No signup required to try.

An HLR lookup answers only for mobile numbers, so check that an Irish number has the shape of a mobile before you ask.
Only mobile lines have an entry in a Home Location Register. These are Ireland's rules from the numbering data.
| Number | What the digits show | What the HLR lookup does |
|---|---|---|
| An Irish mobile | A mobile number has 9 digits after +353, or 10 written at home, starting 08. | Asks the network whether the SIM is on and reachable. Outside the US and Canada the answer usually comes live from the network. |
| An Irish landline | A landline has 7 to 10 digits after +353, starting 01, 02, 04, 05, 06, 07 or 09, such as +353 1 XXXX XXXX. | No status comes back, because a landline has no entry in a Home Location Register. Use the Irish phone number checker for its line type. |
These are the answers an HLR lookup gives for an Irish mobile number, and what to do with each.
The status is the headline of every result. A record read instead of a live query never says that the phone is on.
| Status | What the network is saying | What to do |
|---|---|---|
| Active / reachable | The SIM is registered on a network and can receive a call or SMS now. | Safe to message or call. |
| Temporarily unreachable | The number exists, but the phone may be off or out of coverage. | Keep it and retry later, because it is not a bad number. |
| No active line | The network reports no subscriber on this number. | Remove it from the list. |
| Invalid or not in service | The records have no assigned number like this one. | Remove it from the list, and check the digits first. |
| Assigned | A record shows the number is assigned, and it does not show that the phone is on. | Treat it as a number in use, and check its line type before you text it. |
| Unknown | The network gave no usable answer. | Treat it as unresolved, never as invalid, and check it again later. |
An Irish mobile number is +353 followed by 9 digits, and the first one is 8.

The +353 and the 0 do the same job, so a number is never written with both.
An HLR lookup of an Irish mobile number travels to its network and stops before anything reaches the phone.
This is the path one lookup takes. Outside the US and Canada the answer usually comes from the network that holds the number, which is why it says whether the SIM is on right now.
- You enter the numberType it the way it is written at home, such as 085 012 3456, or paste it with +353. It has to be a mobile.
- Its format is checkedEach type of number has its own rules. A mobile needs 9 digits after +353 and starts with 08 at home.
- The number's own network is askedThe query goes to the network that holds the number and stops before any message is delivered.Stops here: no SMS is delivered and the phone never rings.
- You see the statusActive, temporarily unreachable, no active line or unknown, with the country and the ported flag.
An Irish mobile number has 9 digits after +353 and starts with 08, so any other length is not a valid mobile.
These lengths come from the numbering data for Ireland. A mobile number has 10 digits when it is written at home with its 0.
| Number type | Starts with at home | Digits after +353 | Written at home |
|---|---|---|---|
| Mobile | 08 | 9 | 085 012 3456 |
| Landline | 01, 02, 04, 05, 06, 07 or 09 | 7 to 10 | (01) XXXX XXXX |
Three common mistakes make an Irish number fail the check, and each one is quick to fix.
Keeping the 0 after +353 adds a digit.
The 0 is only for dialing inside Ireland, so +353 085 012 3456 is wrong. Drop the 0 and write +353 85 012 3456.
Typing too few or too many digits makes a number invalid.
A mobile number has 9 digits after +353. With 8 or 10 it cannot be a valid mobile, so look for a missing or doubled digit.
Leaving the wrong country selected changes how the number is read.
The lookup reads a number by the rules of the country selected above, so keep Ireland selected for a +353 number. Paste a number with its + and country code and the country is read from the number itself.
These are the questions people ask most about HLR lookups of Irish phone numbers.
How do I check if an Irish mobile number is active?
Enter the number in the box above with Ireland selected. Type it the way it is written at home, such as 085 012 3456, or with the country code, such as +353850123456. The free tool returns its status, its country and the ported flag, and an active status means the SIM is registered and reachable.
How many digits is an Irish mobile number?
A mobile number has 9 digits after +353, or 10 written at home, starting 08.
Can an HLR lookup check an Irish landline?
No. Only mobile lines have an entry in a Home Location Register, so a landline cannot return a connectivity status. A landline has 7 to 10 digits after +353, starting 01, 02, 04, 05, 06, 07 or 09, such as +353 1 XXXX XXXX. The Irish phone number checker gives the line type of any number.
Does the free HLR lookup show which network an Irish number is on?
The free result shows the status, the country and the ported flag. The current and original carrier come with a free account.
Does an HLR lookup show whether an Irish number was ported?
Yes. The Ported row reads Yes or No when the network answered, and Unknown when it gave no answer. Unknown is not the same as No.
What does temporarily unreachable mean for an Irish mobile number?
The number exists, but the phone may be off or out of coverage right now. That is not the same as an invalid number, so keep it and check it again later.
Is the answer live for Irish numbers?
Outside the US and Canada a mobile number usually gets a live answer from the network that holds it. When the lookup reads number records instead, the result says assigned, which means the number is in use and not that the phone is on.
Can I run an HLR lookup on a whole list of Irish mobile numbers?
Yes. This free tool checks one number at a time. A 7-day free trial opens CSV upload and the API, at 5 credits a number, and a number the network reports as invalid is not charged.
Does the person know I ran an HLR lookup on their number?
No. No SMS is sent and the phone never rings, so its owner is never told.
You can check mobile numbers from other countries on their own pages.
