9876543210       True
+91 9123456789   True
+91-8123456789   True
5123456789       False
98765            False

Approach

1. (\+91[\s-]?)?[6-9]\d{9}.

Solution

import re for n in ["9876543210", "+91 9123456789", "+91-8123456789", "5123456789", "98765"]:    print(n.ljust(16), bool(re.fullmatch(r"(\+91[\s-]?)?[6-9]\d{9}", n)))

9876543210       True
+91 9123456789   True
+91-8123456789   True
5123456789       False
