There is no area code 890 currently assigned in the North American Numbering Plan (NANP). Area codes in this numbering plan are assigned to specific geographic regions in the United States, Canada, and other territories.
It’s possible that 890 could be a future area code, or it might be a special service code that is not widely used for regular geographic regions.
If you encounter this number in relation to phone calls or messages, ensure it is not a scam or misdialed number. Always verify unfamiliar area codes using official telecommunications resources.
