E-commerce by province 2025: Provincial volume and business counts from Ministry of Trade data

E-commerce sales, purchases, and business counts for 81 provinces (2025)

According to Table 9, 5 provinces exceeded 100 billion TL in e-commerce sales in 2025: Istanbul, Ankara, İzmir, Kocaeli, and Bursa. The table below presents the 81 provinces in the same order as the report’s Table 9; the e-commerce adaptation index score and rank in parentheses in the final column were taken from Table 8.

Source: Republic of Türkiye Ministry of Trade, Outlook of E-commerce in Türkiye Report 2025, Table 9 (pp. 78–80) and Table 8 (pp. 74–76). Amounts are given in billion TL to two decimal places in the report. Adding sales for the 81 provinces in Table 9 produces 4,268.29 billion TL, and adding purchases produces 3,763.19 billion TL (Onur Freelance calculation); the report does not explain why these totals differ.

Istanbul e-commerce volume: 65.9% of total sales across 81 provinces

Istanbul recorded 2,813.09 billion TL in e-commerce sales and 1,585.94 billion TL in e-commerce purchases in 2025. This sales amount represents 65.9% of total sales across the 81 provinces in Table 9; sales in second-ranked Ankara (288.79 billion TL) represent 6.8% of the total (Onur Freelance calculation).

The top five provinces (Istanbul, Ankara, İzmir, Kocaeli, and Bursa) together account for 82.0% of the 81-province total with 3,498.55 billion TL in sales. In seven provinces (Ardahan, Bayburt, Gümüşhane, Hakkâri, Iğdır, Kilis, and Tunceli), annual e-commerce sales remain below 1 billion TL (Onur Freelance calculation from Table 9).

According to Table 8, Istanbul’s sales are 177.38% of its purchases; domestic e-commerce is 15.49% of provincial GDP, and businesses engaged in e-commerce are 22.43% of all businesses in the province. E-commerce volume per business is 10.50 million TL, ranking second after Çorum (11.17 million TL). Istanbul’s weight is also visible in delivery: 53.5% of e-commerce shipments originate in Istanbul (Chart 66, p. 126), and Tuzla is the district sending the most shipments with 8.7% (Chart 67, p. 127).

In the report’s chart of average interprovincial parcel delivery times, the shortest time is 20 hours for shipments from Sakarya to Istanbul, followed by Ankara→Istanbul (20.5 hours) and Kocaeli→Istanbul (20.8 hours) (Chart 70, p. 128).

E-commerce adaptation index: How are provinces ranked?

Istanbul ranks first in the adaptation index with 93.10 points, and Iğdır ranks last with 25.03 points. According to the report, the index measures a weighted average of four variables rather than absolute volume: sales coverage of purchases, provincial e-commerce as a proportion of GDP, e-commerce volume per business, and businesses engaged in e-commerce as a proportion of all businesses in the province. The report does not provide the variable weights.

The top 10 provinces in order are Istanbul (93.10), Çorum (71.03), Kayseri (69.62), Kocaeli (69.38), Ankara (64.90), İzmir (64.49), Bursa (63.35), Gaziantep (58.52), Eskişehir (58.51), and Adana (58.01). The 5 lowest-scoring provinces are Hakkâri (27.72), Kırşehir (27.38), Bitlis (25.73), Tunceli (25.06), and Iğdır (25.03).

Çorum’s second-place position results from the index methodology. In Çorum, sales are 180.96% of purchases, and volume per business is 11.17 million TL, the highest among 81 provinces. According to the report’s footnote, provinces with strong production and logistics capacity, access to external markets, and few but high-performing businesses can score highly even without large total volumes (Table 8 explanation, p. 77).

Selling provinces and purchasing provinces: Coverage ratio

In 77 of the 81 provinces, e-commerce purchases exceed sales; the only provinces whose sales exceed purchases are Çorum, Istanbul, Kayseri, and Kocaeli. The coverage ratio (sales/purchases) indicates e-commerce sales in a province as a proportion of e-commerce purchases in that province.

After these four provinces, the highest ratios are in Ankara (94.05%), Bursa (87.67%), İzmir (86.07%), Gaziantep (82.72%), and Aydın (80.58%). The lowest ratios are in Iğdır (15.72%), Tunceli (15.95%), Hakkâri (17.35%), and Bitlis (17.66%). In Antalya, the ratio is 60.59%: provincial e-commerce purchases are 122.67 billion TL and sales are 74.33 billion TL. Antalya ranks 4th in purchases and 6th in sales (Onur Freelance ranking based on Table 9 values).

Istanbul, Ankara, İzmir, Bursa, Antalya, Kocaeli, Sakarya, and Tekirdağ

These 8 provinces account for 84.4% of total e-commerce sales across 81 provinces (Onur Freelance calculation). Values from Tables 9 and 8 are presented side by side below:

Provincial e-commerce shares during the November campaign month

During the November 2025 campaign month, 67% of marketplace sales volume belonged to sellers in Istanbul, and 31% of purchase volume to buyers in Istanbul. Kayseri and Gaziantep appear only in the seller list; Konya and Mersin appear only in the buyer list:

Source: Table 5 and Table 6 (p. 54). Both tables cover marketplaces only; sales businesses make through their own websites are not included in these shares. The report provides only the top 9 provinces in both tables.

Quick commerce and shipping: Provincial delivery data

Istanbul accounts for 55.4% of quick commerce volume and 53.5% of e-commerce parcel shipments. According to the report, in 2025, 69.5% of quick commerce took place in meal delivery and 30.5% in food and supermarkets (Chart 46, p. 87).

• Quick commerce volume share (Table 10, p. 90): Istanbul 55.4%, Ankara 8.1%, İzmir 7.0%, Bursa 3.7%, Antalya 3.0%, Kocaeli 2.0%, Adana 1.5%, Mersin 1.5%, Eskişehir 1.2%, Muğla 1.0%.
• Provinces sending shipments (Chart 66, p. 126): Istanbul 53.5%, Ankara 7.5%, Kocaeli 7.3%, İzmir 5.9%, Bursa 3.5%.
• Provinces receiving shipments (Chart 68, p. 127): Istanbul 27.9%, Ankara 8.7%, İzmir 6.8%, Kocaeli 4.7%, Bursa 3.9%, Antalya 3.7%.
• Within-city delivery rate (Chart 72, p. 131): Türkiye overall 17%, Istanbul 28%, Ankara 11%, İzmir 10%, Bursa 5%, Kocaeli 4%.

Geography is decisive in delivery time. According to the report, parcels sent to and from the Doğu Anadolu Region generally take longer to deliver than in other regions; the longest average delivery time was measured for shipments from Bitlis to Muğla (Chart 71 and Maps 5–6, pp. 129–130).

What do these data tell a business starting e-commerce? (Interpretation)

This section is Onur Freelance’s interpretation, not the Ministry’s assessment. The main picture from the provincial tables is that sales concentrate in a few provinces, while buyers are spread more widely across the country.

• Buyers in every province: 57.9% of total purchases across 81 provinces are in the 80 provinces outside Istanbul (Onur Freelance calculation). Shipping and delivery-time planning should account for every destination province, not just the province where the business is located.
• Delivery-time information: Knowing that parcels to Doğu Anadolu take longer to deliver, clearly stating estimated delivery times by region on product and shipping pages sets customer expectations correctly.
• Volume is not the only criterion: The Çorum example shows that high volume per business is possible even with few businesses. Being outside a large city should not be considered an obstacle to e-commerce on its own.
• Dependence on a single channel: The campaign-month tables measure marketplaces only. A business with its own website can also track sales outside marketplaces using its own data.

Methodology, limitations, and updates to this page

The report PDF was downloaded on October 11, 2026, its text was extracted using pdftotext, and Tables 8 and 9 were parsed with a script. The two tables were cross-checked: the sales/purchases ratio and volume per business calculated from Table 9 matched Table 8 values for all 81 provinces. Page numbers are the report’s printed page numbers; provincial shares, rankings, and totals are Onur Freelance calculations and identified as such in the text.

Limitations

• The report has no provincial transaction (order) counts; this page provides only provincial amounts, business counts, and ratios.
• The report does not separately explain how sales and purchases are assigned to provinces (seller headquarters, warehouse, delivery address).
• Sales and purchase totals across 81 provinces differ from one another and from Türkiye-wide e-commerce volume; provincial shares were calculated against the 81-province total and should not be read as shares of national volume.
• Campaign-month, quick commerce, and shipping data are available only for the top 5–10 provinces given in the report; provincial map values were not used because they could not be matched to province names.
• Per-capita e-commerce amounts were not derived; population data were not added to this page.
