Next step
A 458 number tells you where it was issued, not what it is now.
Mobiles, landlines and VoIP lines share area codes, and numbers move between carriers. A live line-type and carrier lookup on every number in your list says which is which, and that decides which calling and texting rules apply. It's in the phone add-on.

Area code 458 questions
- What state is area code 458?
- Area code 458 is in Oregon, United States. Its largest rate centers by number of prefixes are Eugene, Bend, Albany, Medford and Grants Pass.
- What time zone is area code 458 in?
- Mountain Time and Pacific Time. The code crosses a time zone line, so the local time depends on where in the area the number was issued.
- What area codes overlay 458?
- 541. An overlay adds a new code to the same area instead of splitting it, so neighbours can have different area codes and local calls need 10 digits.
- When did area code 458 start?
- Area code 458 went into service on February 10, 2010 as an overlay of 541.
- Is a 458 number a cell phone or a landline?
- The area code can't tell you. In the US and Canada mobiles, landlines and VoIP lines share area codes and prefixes, and numbers move between carriers and line types. Only a live line-type lookup answers it for one number.
- How many phone numbers does area code 458 have?
- 214 of its 792 possible prefixes are in service, and each prefix holds up to 10,000 numbers. That counts prefixes assigned to carriers, not numbers in use.
- Does a valid format mean a 458 number is in service?
- No. A format check only says the digits fit the North American Numbering Plan and that 458 is an assigned code. It cannot tell whether the number is connected, who answers it or which carrier serves it today, because numbers are reassigned and ported. A live carrier lookup reports the current carrier and line type, but even that is not proof someone answers.
- Can I check a list of 458 numbers for free?
- Yes. Paste them in the list tab above or upload a CSV to the bulk phone number validator: format, E.164, country and the numbering-plan line type are free for every row, with no account. Live carrier and line-type lookups come with Pro + Phone at $49.99/mo (5,000 a month).
