Shopify Flow vs Ultimate Postal Code Blocker

Ultimate Postal Code Blocker edges out Shopify Flow on rating (5.0★ vs 4.7★), but the gap is small enough that pricing fit and feature differentiation should drive the decision more than the headline number.

Pricing entry tiers: Shopify Flow at Free, Ultimate Postal Code Blocker at Free trial available. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (seats, usage volume, integrations) varies.

Shopify Flow has the larger user base (13,709 reviews vs 3), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns. Ultimate Postal Code Blocker's smaller cohort can be an advantage for niche workflows where the bigger app has accumulated bloat.

Recommended by size: small/early-stage merchants who need fast install and low risk should default to Ultimate Postal Code Blocker; mid-market and enterprise merchants with specific feature requirements should evaluate both — Shopify Flow's 13,709-review base may include the workflow context that matches your specific use case better than Ultimate Postal Code Blocker's broader-but-shallower coverage.
