Postal Code Shopify Apps – Analytics & Insights

Ultimate Postal Code Blocker ranks #1 for postal code with 2.8% share — the leader position in a fragmented field where many apps are within striking distance, -16.4pp ahead of SMART Shipping Rates & Rules (19.3%). Releasit COD Form & Upsells sits at #3 with 66.9% share, rounding out the top tier. Together, the top 3 apps absorb 89.0% of all postal code installs — a highly concentrated landscape with limited room for new entrants. Releasit COD Form & Upsells is the standout mover this month, climbing 2 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.

Postal Code is a fragmented market — the top 3 apps together hold only 89.0% of installs, leaving Ultimate Postal Code Blocker's 2.8% lead modest in absolute terms and Releasit COD Form & Upsells at 66.9% still capturing meaningful share. With this many viable apps, pricing model and integration depth differentiate postal code options more than rank does.

Ultimate Postal Code Blocker climbed from #6 (Oct 2025) to #1 (Oct 2026) — a 5-position gain among postal code apps over the charted window. Across the top 5 plotted postal code apps, 3 improved their ranking while 2 declined — the category is moving upward overall. Ultimate Postal Code Blocker's share held near 2.9% from Oct 2025 to Oct 2026 — a stable install base for postal code apps rather than active gain or loss.

A 5-position move for the leader over the charted postal code window is large enough to reflect real merchant adoption shifts, not just App Store noise — Ultimate Postal Code Blocker's climb as of Oct 2026 is the strongest trajectory signal in this chart.

Colombia is the largest single market for postal code apps at 20.2% — but no country dominates, meaning postal code apps serve a globally distributed merchant base. United States follows at 13.2%, with Chile at 7.7%. Together, the top 3 markets account for 41.1% of postal code app installs worldwide. Spain (6.7%) and Mexico (4.7%) round out the top 5.

With Colombia's 20.2% as the largest single market and the rest spread across many countries, the leading postal code apps tend to be region-agnostic by design — geography matters less for app choice here than features, pricing, and support quality.

Releasit COD Form & Upsells reached 1,000 reviews in 46 months since launch — the fastest ramp among the top 5 postal code apps tracked here. Pickup Delivery Date Pickeasy crossed the same milestone in 69 months, 23 months behind.

3 apps on this chart haven't yet crossed 1,000 reviews: SMART Shipping Rates & Rules at 465, HideShip:Hide Shipping Methods at 91, Ultimate Postal Code Blocker at 13 cumulative reviews. SMART Shipping Rates & Rules is closest to the milestone — its current count puts it roughly 47% of the way to 1,000.

The 23-month spread between Releasit COD Form & Upsells and Pickup Delivery Date Pickeasy reaching 1,000 reviews suggests a competitive postal code category — leaders pulled ahead by roughly a year, but no single app dominated launch-to-milestone speed. The ramp differences likely reflect both product quality and timing-of-launch rather than one clear category winner.
