How do I dial mobiles vs landlines in Slovakia

Slovakia’s country calling code is +421. Slovakia uses a closed numbering plan where domestic geographic (landline) numbers are typically written with a leading 0 before the area code, such as 02 for Bratislava and 055 for Košice. When calling within Slovakia, you’ll commonly dial the full domestic form (including the leading 0 + area code + subscriber number). When calling from abroad, you dial +421 and drop the leading 0 from the area code—so 02… → +421 2… and 055… → +421 55….

Mobile numbers are also usually written domestically with a leading 0 and start with 09… (for example 0905…). Internationally, you dial them as +421 9XX XXX XXX (again, drop the leading 0). A good best practice for travelers and for messaging apps is to store Slovak numbers in E.164 format: +421 plus the rest of the number without the domestic trunk 0—this prevents failed calls when roaming or dialing from outside Slovakia.

What are the emergency numbers in Slovakia

Dial 112 for general emergencies. Slovakia also uses 150 (fire & rescue), 155 (ambulance), 158 (police), and 159 (municipal police).

What are the city and area codes in Slovakia

Dialing tip: In Slovak domestic writing, you’ll often see area codes with a leading 0. For international calls, remove that 0 and dial +421 instead. Bratislava is a common exception in formatting because it uses area code 2 with a longer subscriber part.

Which mobile prefixes do mobile operators use in Slovakia

Dialing tip: Slovakia supports number portability, and the regulator maintains detailed portability rules—so prefixes like 0905 or 0940 are helpful as a “typical allocation,” but they don’t guarantee the current operator.

Mobile Operator	Dialing Prefixes
Slovak Telekom	0901–0904, 0910–0912, 0914
Orange Slovensko	0905–0908, 0915–0919, 0945
O2 Slovakia	0940, 0944, 0947–0949
