Pro Tips for OfferUp Verification

Maximize your success

Keep both tabs open side-by-side: OfferUp on one side, ProxNum dashboard on the other.
Rental numbers are ideal if OfferUp sends periodic sign-in alerts or account-recovery codes over time.
Enter the number exactly as shown in your dashboard, country-code prefix included.
Use a VPN matching your virtual number's country for smoother acceptance on geo-sensitive OfferUp features.
If OfferUp reports the number as 'invalid', the number format is likely missing the '+' prefix — double-check.
Always select 'SMS' — not 'phone call' — in OfferUp for the fastest code delivery.
Bulk purchasing credits before a big batch of OfferUp sign-ups can reduce per-verification costs.
Trigger the SMS in OfferUp before you switch back to check your dashboard — codes often pre-load.
