Outside the United States, "Boulevard of Broken Dreams" charted strongly on many international charts. The song debuted and peaked at number five on the UK Singles Chart on the chart dated December 5, 2004, giving the band their third top 10 single in that country. It stayed in the UK top 100 for 29 weeks, becoming their longest-charting single at the time, but "Wake Me Up When September Ends" would log 32 weeks in the UK top 100 nearly a year later; it remains their second-longest stay on the UK chart. In 2019, the British Phonographic Industry awarded the song a Gold certification for exceeding sales and streams of 400,000. The single was successful in Ireland, reaching number two in January 2005 on two separate occasions and totaling 23 weeks in the top 50. It was their highest-peaking single there until "The Saints Are Coming" topped the Irish Singles Chart in 2006. Elsewhere in Europe, the song reached number one in the Czech Republic, number two in Sweden, and the top 10 in Austria, Denmark, and Norway. In Australasia, the song reached number five in both Australia and New Zealand. It stayed on the latter country's chart longer, remaining on the RIANZ chart for 25 weeks compared to 17 weeks on the ARIA Singles Chart. Despite this, the song was overall more popular in Australia, finishing 2005 as the 31st best-selling single and earning a Platinum certification from the ARIA for sales exceeding 70,000 copies.
